Hinge module of portable wireless terminal {HINGE MODULE FOR PORTABLE RADIOTELEPHONE}

The present invention relates to a hinge module of a portable wireless terminal, and more particularly, to a hinge module of a portable wireless terminal configured to automatically open a sub-body installed to be opened and closed at a predetermined angle from the main body by only a button operation installed on the terminal.

In recent years, due to the development of the electronic communication industry, portable wireless terminals are becoming smaller and thinner, and their functions are diversifying. In addition, terminals having various configurations are being released to meet various needs of users.

Recently, a folder type or a flip-up type comprising a main body, which is a main body rather than a bar type, and a sub body installed to be opened and closed at a predetermined angle by a predetermined hinge module on the main body. Flip-up type terminals are becoming mainstream. The reason for using such a folder type terminal is that the sub-body (including the flip cover or folder) connected to the main body protects a number of key buttons formed on the main body to prevent the malfunction of the device and plays the role of a negative reflector during a call. Because it collects the notes. Furthermore, in the folder type terminal, the wide LCD module can be separately mounted in the folder, which is advantageous in miniaturizing the product and in implementing a variety of functions.

Typically, the folder type terminal is equipped with a hinge module for opening and closing the sub body at a predetermined angle on the main body. The hinge module not only designates the opening / closing angle of the sub body, but also when it is folded, it also stores a certain elastic force so that the hinge module does not open arbitrarily.

In the opening / closing operation of the folder type terminal, the user generally opens the main body with one hand while holding the sub body with the other hand to apply a predetermined force.

However, as described above, the structure of opening the terminal using both hands is inconvenient to open the terminal when the user uses only one hand, for example, when driving or unhandling one hand. When one-handed operation, the folder opens and closes randomly, causing communication problems.

In order to solve the above problems, it is an object of the present invention to provide a hinge module of a portable wireless terminal configured to allow a user to easily open a folder with only one hand.

Another object of the present invention is to provide a hinge module of a portable wireless terminal configured to easily open a folder in a main body only by operating a button configured outside the terminal.

Still another object of the present invention is to provide a hinge module of a portable wireless terminal configured to enable smooth communication between users by preventing any phenomenon of opening of a folder in advance.

Preferably, the folder opening and closing button 60 may be installed on the same straight line as the hinge axis (axis A of FIG. 1) in which the hinge module 10 of the terminal 100 is installed.

Figure 3 is an exploded perspective view showing the configuration of the hinge module according to an embodiment of the present invention, Figure 4 is a partial cross-sectional view showing a state in which the hinge module according to an embodiment of the present invention is mounted on the terminal, The hinge module 10 according to the present invention includes a hinge housing 20 installed at the center hinge arm of the folder, a hinge cam 30, a hinge spring 50, and a rotation shaft sequentially received in the hinge housing 20. It consists of 40.

The outer surface of the hinge housing 20 is formed in a structure for flowing with the opening and closing operation of the folder (120 of FIG. 1). In the present invention, the upper outer surface of the illustrated hinge housing 20 is formed to have a stage, but other methods may be used. The hinge housing 20 is formed with an accommodating portion 21 for accommodating the hinge cam 30, the hinge spring 50, and the rotation shaft 40 described above, and a part of the accommodating portion 21 is opened. It is formed to be. Predetermined through holes 22 and 23 are formed on both sides of the accommodating part 21, and on one side, a predetermined mountain part 25 to be coupled with the valley part 32 of the hinge cam 30 to be described later. Hinge shaft 24 having a) protrudes in the direction of the receiving portion (21). In addition, the housing 21 of the hinge housing 20 has a predetermined width for guiding the projection 34 formed in the hinge cam 30 so that the hinge cam 30 flows back and forth only in the axial direction. The same guide groove 26 is formed.

The hinge cam 30 has a cylindrical body 31 in which a pair of opposite valley portions 32 and a pair of mountain portions 33 are formed, and protrudes on one side of the body 31 and the hinge housing. It consists of the shaft 35 which penetrates the through-hole 22 formed in the accommodating part 21 of 20, and is fixed to a main body. The diameter of the shaft 35 is formed to be smaller than the diameter of the body 31 so that the hinge cam 30 is interrupted in the receiving portion 21 of the hinge housing 20. In addition, the hinge cam 30 is also fixed to the main body while being able to flow only in the axial direction (A direction of FIG. 1).

The rotary shaft 40 is formed to rotate with the hinge housing 20. A locking portion 41 is formed to be caught by the through hole 23 of the hinge housing 20, and a shaft 43 penetrating through the through hole 23 is formed at one side of the locking portion 41. On the other side, a shaft 45 having a predetermined length is installed, and a part is inserted into one end of the spring 50 to be described later. At this time, at least one predetermined seating groove 42 is formed at one side of the locking part 41, and a protrusion 27 for seating in the seating groove 42 is formed on the side wall of the hinge housing 20. Is formed to protrude. Therefore, when the rotary shaft 40 is mounted on the accommodating portion 21 of the hinge housing 20, the protrusions 27 of the hinge housing 20 are seated in the seating grooves 42 of the rotary shaft 40. As a result, the hinge housing 20 rotates together. In other words, when the hinge housing 20 fixed to the folder rotates with the folder, the rotary shaft also rotates together. However, since the hinge cam 30 is fixed to the main body, it does not rotate.

Thereafter, a predetermined hinge spring 50 is interposed between the rotary shaft 40 and the hinge cam 30. The hinge spring 50 uses a compression coil spring to press the hinge cam 30 and the rotation shaft 40 in opposite directions. One end of the hinge spring 50 is formed to be caught by the catching hole 46 of the shaft 45 formed in one end of the rotary shaft 40, the other end is protruded in one end of the hinge cam 30 It is installed so as to be caught by the engaging hole 37 of the. In addition, the hinge spring 50 is installed to have a torsion force in a predetermined direction when initially mounted. Preferably, the torsion force of the hinge spring 50 is installed to be applied in the direction in which the folder is opened. More preferably, the torsional force when the folder is completely closed is installed to be greater than the torsional force when the folder is fully open. However, the torsion force may be a force that does not exceed the mountain portion 25 formed in the hinge housing 24 riding the bone portion 32 of the hinge cam 30 described above.

In addition, the shaft 43 protruding through the through hole 23 of the hinge housing 20 of the rotary shaft 40 may be dummy coupled to the terminal body, and a predetermined screw groove 44 is formed at an end thereof. ) May be formed. Therefore, the user pushes the rotary shaft 40 in the direction of the receiving portion 21 of the hinge housing 20 with a driver or the like, and the protrusions 27 of the hinge housing 20 and the seating grooves 42 of the rotary shaft 40. By separating and rotating in a predetermined direction it is possible to adjust the torsion force of the hinge spring (50).

As shown in FIG. 4, the shaft 35 of the hinge cam 30 penetrating through the hinge housing 20 is fixed to the main body, and at its end is interlocked with a predetermined button end that partially protrudes from the main body 110. It is installed as possible. The button 60 is a button for opening and closing the folder, and when the button 60 is pressed, the hinge cam 30 flows in the direction in which the button 60 presses the button 60.

FIG. 5 is a partial cross-sectional view illustrating a state in which the hinge cam retreats backward as the folder is opened according to an exemplary embodiment of the present invention. In the process of folding the folder 120, the hinge housing together with the folder 120 is illustrated. 20 rotates. At this time, the mountain portion 25 formed in the hinge shaft 24 of the hinge housing 20 is carried over the valley portion 32 of the hinge cam (30). However, since the hinge cam 30 is installed to flow only in the axial direction, the hinge cam 30 is pushed backward by the ridge 25 of the hinge housing 20. In this case, the hinge spring 50 stores a predetermined torsion force, which is rotated together with the hinge housing 20 by the rotary shaft 40 to which one end of the hinge spring 50 is fixed, and the hinge spring 50. This is because the hinge cam 30 of which the other end is fixed does not rotate, and at the same time, the hinge spring 50 presses the hinge cam 30 pushed backward.

Then, when the folder 120 is completely closed, the valleys 32 of the hinge cam 300 and the ridges 25 of the hinge shafts 24 formed on the hinge housing 20 are engaged with each other as shown in FIG. 4. In this case, the hinge spring 50 stores the torsion force for opening the folder 120. However, the torsion force of the hinge spring 50 is the mountain 25 of the hinge housing 20. As shown in FIG. ) Is so strong that it cannot ride over the bone 32 of the hinge cam 30. That is, the folder 120 can continuously maintain the folded state.

Then, when the user uses the terminal or needs to open the folder 120, the user presses the folder opening / closing button 60 formed on one side of the terminal. Accordingly, the folder opening and closing button 60 pushes the shaft 35 of the hinge cam 30 penetrating the hinge housing 20 to the rear. In this case, the hinge spring 50 which is artificially stored. ) To the state of releasing the torsion force. That is, since the valley portion 32 of the hinge cam 30 releases the mountain portion 25 of the hinge housing 20 at random, the hinge is centered around the hinge cam 30 installed so as not to flow and rotate only in the axial direction. The housing 20 rotates with the folder 120. That is, the folder 120 is automatically opened only by pressing the button 60 installed outside the terminal.

On the other hand, the configuration of the valley portion 32 of the hinge cam 30 and the mountain portion 25 of the hinge housing 20 may be interchanged. For example, a hinge cam having a valley portion may be formed on the hinge housing 20, and a hinge shaft having a hill portion engaged therewith may be provided.

Apparently, there are many ways to modify these embodiments while remaining within the scope of the claims. In other words, there may be many other ways in which the invention may be practiced without departing from the scope of the following claims.

The present invention has the effect that the user can operate the terminal with only one hand because the folder is opened only by the button operation installed on the outside of the terminal.
