Description

Sliding type portable wireless terminal {SLIDING TYPE PORTABLE WIRELESS TERMINAL}

The present invention relates to a portable wireless terminal, and more particularly, to a sliding type portable wireless terminal that opens and closes a keypad of a main body by sliding the subbody in the longitudinal direction of the main body.

Typically, portable wireless terminals are classified into bar type, flip type, and folder type terminals according to their appearance.

The bar terminal is a type in which a data input / output means and a handset are mounted in a main body housing, and a keypad, which is a data input means, is always exposed, which may cause a malfunction. There is a limit to miniaturization.

The flip terminal comprises a main body, a flip, and a hinge module that connects the main body and the flip. The flip terminal is provided with a data input / output means and a handset, and the flip is a keypad for the data input means. The cover can prevent malfunction, but the flip type terminal also has a limitation in miniaturization due to the problem of securing the distance between the transmitter and the receiver.

The folder-type terminal includes a main body, a folder, and a hinge module for rotatably connecting the main body and the folder to be opened and closed by rotating the folder. When the folder is in close contact with the main body, the keypad is placed in a call-waiting mode. Malfunctions can be prevented, and in the call mode, the folder can be opened to sufficiently secure the distance between the transmitter and the receiver, which is advantageous in miniaturization. For this reason, the foldable terminal is gradually becoming the mainstream of the portable wireless terminal.

The flip type terminal or the folder type terminal is provided with a force in a direction in which the flip or folder is opened without further applying a force when the flip or folder rotates by a predetermined angle from the main body by a hinge module rotatably coupled to the main body. Below the angle is provided with a force in the direction in close contact with the body.

Meanwhile, as the design of portable wireless terminals is diversified, sliding type portable wireless terminals composed of sub-bodies that open and close a keypad installed on the main body by sliding on the main body are newly introduced and gradually commercialized.

However, the proposed structure for implementing a sliding type portable wireless terminal is extremely insignificant, and furthermore, there is an inconvenience in that the user has to manually operate the subbody to open and close the subbody.

In order to solve the above problems, it is an object of the present invention to provide a sliding type portable wireless terminal that can easily open and close the sub-body.

In order to achieve the above object, the present invention provides a sliding type portable wireless terminal having a main body and a sub body which is opened and closed in the longitudinal direction of the main body,

The sub-body 102 is slidably coupled on the main body 101 and includes a speaker unit 117 (shown in FIG. 8), a liquid crystal display (LCD), and a TFT having a speaker phone in the front side thereof. The display device 115 and predetermined function keys 119, which can be configured in various forms such as a thin film transistor (TFT), are provided. The rear of the sub-body 102 is provided with a pair of sliding guides 127 for smooth sliding movement. As shown in FIG. 3A, the sliding guide 127 preferably has an H-beam shape in which side grooves 127a are formed. The sliding of the sub-body 102 is guided by the H-beam shape, and at the same time, the sub-body 102 is prevented from being separated from the main body 101. In order to separate the subbody 102 from the main body 101, the subbody 102 must be moved in the longitudinal direction of the main body 101. The sliding guide 127 is fixed to the coupling groove 123 formed in the longitudinal direction on the rear surface of the sub-body 102.

The spring module 150 includes a rear cover 151, a front cover 153, and a torsion spring 155.

The rear cover 151 is fixed to the front of the main body 101. The rear cover 151 may be manufactured separately from the main body 101 to form a spring module 150 or may be integrally formed on the main body 101. The rear cover 151 is positioned above the front of the main body 101, and the keypad 111 is positioned below the front of the main body 101. In addition, as shown in FIG. 2, the rear cover 151 is formed with a spring groove 151a that provides a space in which the torsion spring 155 may flow. The spring groove 151a is provided with an inner wall 151b and an outer wall 151c.

The front cover 153 has a sliding groove 153d corresponding to the sliding guide 127 in the longitudinal direction, and a guide slit 153c penetrating the inner side of the sliding groove 153d and the front cover 153. ) Is formed in the longitudinal direction. As shown in FIG. 3B, the slider 153e provided at the end of the sliding groove 153d moves in the side groove 127a of the sliding guide 127. The upper surface of the sliding guide 127 communicates with the inside of the front cover 153 through the guide slit 153c. In addition, the front cover 153 is formed with a support hole 153f for supporting the torsion spring 155. The front cover 153 is fixed to the rear cover 151 and coupled to the sliding guide 127 at the rear of the subbody 102 to slidably connect the main body 101 and the subbody 102 to each other. It will act as a bridge.

The torsion spring 155 includes a coil 155a, a first fixed end 155b extending from one end of the coil 155a, and a second fixed end 155c extending from the other end of the coil 155a. ) Is provided. The coil 155a of the torsion spring 155 moves along a predetermined trajectory within the spring groove 151a of the rear cover 151. The first fixing end 151b protrudes outward through the guide slit 153c of the front cover 153. The first fixing end 155b protruding through the guide slit 153c is fixed on the sliding guide 127 behind the subbody 102, and the second fixing end 155c is the front cover 153. ) Is fixed to the support hole 153f. The torsion spring 155 accumulates an elastic force acting in a direction away from the first fixing end 155b and the second fixing end 155c, and the elastic force is such that the subbody 102 causes the main body 101 to move away. Opening and closing the keypad 111 and the transmitter 113 on the top. Since the torsion spring 155 is easy to reduce the thickness, it is advantageous for the slimming of the spring module 150 for implementing the sliding operation of the sub-body 102.

4 and 5 are views for explaining the operation of the torsion spring 155. 4 illustrates a state in which the subbody 102 closes the keypad 111 and the talker 113 of the main body 101. In the state in which the main body 101 is closed, the first fixing end 155b of the torsion spring 155 is positioned below the guide slit 153c.

When the user moves the subbody 102 to the upper side of the main body 101 in the state in which the main body 101 is closed, the first fixed end 155b and the second fixed end 155c gradually increase. As it approaches, the torsion spring 155 accumulates elastic force. When the subbody 102 further moves above the main body 101 so that the first fixed end 155b and the second fixed end 155c pass closest to each other, the user may move to the subbody 102. The first fixing end 155b and the second fixing end 155c are separated from each other by the elastic force accumulated in the torsion spring 155 without further moving). That is, when the user moves the sub body 102 by a certain distance, the sub body 102 opens the keypad 111 and the talker 113 of the main body 101 even when no force is applied. In addition, when the keypad 111 and the talker 113 of the main body 101 are open, the sub-body 102 is moved to the lower side of the main body 101 so that the first fixed end 155b. ) And the second fixing end 155c closest to each other, the subbody 102 is moved to the main body 101 by the elastic force of the torsion spring 155 even if the user does not move the subbody 102 further. ), The keypad 111 and the talker 113 are closed.

Looking at the change in the elastic force accumulated in the torsion spring 155 while the sub-body 102 opens or closes the keypad 111 and the talker 113 of the main body 101, the sub-body 102 The elastic force accumulated in the torsion spring 155 is minimal when the main body 101 is fully opened or closed, and the sub-body 102 opens or closes the main body 101. During the process, when the first fixing end 155b and the second fixing end 155c are closest to each other, the elastic force accumulated in the torsion spring 155 becomes the maximum.

As a result, when the sub-body 102 moves and passes the closest position between the first fixed end 155b and the second fixed end 155c, the torsion spring (3) may move along the direction in which the sub-body 102 moves. The main body 101 is opened or closed by the elastic force of 155. That is, when the subbody 102 is located within a predetermined distance from the main body 101, the sub body 102 is provided with a force in the closing direction, and when the sub body 102 is located within a range other than the predetermined distance, the sub body 102 receives a force in the open direction. The opening and closing operation is implemented.

The coil 155a of the torsion spring 155 moves in a curve trajectory within the spring groove 151a. In this case, if an obstacle (not shown) such as a rib restricting the movement trajectory of the coil 155a is installed in the rear cover 151, the movement range of the subbody 102 may be limited. By limiting the moving range of the coil 155a, a part of the shock generated in the opening and closing operation of the subbody 102 may be configured to be absorbed by the torsion spring 155.

On the other hand, while the spring module 150 is accommodated in the rear surface of the sub-body 102, a seating groove 121 for providing a moving space of the spring module 150 is formed. Sidewalls 125a and 124b are formed at the top and bottom of the seating groove 121, respectively, and are in contact with the top end 153a and the bottom end 153b of the spring module 150, respectively. That is, in the state in which the main body 101 is closed, the upper side wall 125a of the seating groove 121 and the upper end 153a of the spring module 150 come into contact with each other, and the main body 101 is opened. The bottom side wall 125b of the seating groove 121 and the bottom end 153b of the spring module 150 come into contact with each other. Thus, the travel distance of the subbody 102 is limited by the spring module 150.

At this time, as described above, by limiting the trajectory of the coil 155a, the lower side wall 125b of the seating groove 121 and the lower end 153b of the spring module 150 when the subbody 102 is opened. Shock generated between the torsion spring 150 may be configured to be absorbed. In addition, in order to secure the reliability of the product, it may be provided with a separate shock absorber (not shown) such as a damper (rubber) in the position where the direct impact occurs.
