Cell phone opening and shutting hinge system of slide type

The present invention relates to a hinge device for opening and closing a mobile phone of a slide type, and more particularly, a first unit having a plurality of key buttons, and a second unit having a display unit that is slidably movable in a first unit thereof. In the sliding type mobile phone opening and closing hinge device for connecting the unit and the first and second units, the hinge pin is excluded and the elastic force of the elastic member is prevented from being concentrated, thereby improving the reliability of the hinge device. And a hinge device for opening and closing a slide type mobile phone.

As is well known, as the spread of portable wireless terminals (hereinafter referred to as 'mobile phones') has expanded worldwide, mobile phones with various functions and designs are being released to meet consumer tastes. Telephones have evolved from bar-type cell phones to flip-type cell phones. In recent years, folders and slide types have become mainstream.

The slide-type mobile phone is an operation structure in which a second unit having a display unit is slidably moved by a predetermined length in a longitudinal direction and opened on a first unit having a keypad equipped with a plurality of key buttons. Push and pull to make it easier to use.

Accordingly, the slide-type mobile phone is preferred as a high-end type because it can implement a miniaturization of the mobile phone while having a display unit similar in size to a folder-type mobile phone.

Such a slide-type mobile phone is configured to automatically move by the opening and closing device as much as the remaining length when the second unit is pushed beyond the predetermined length, and the whole opening and closing device is being developed in various ways.

Such an opening and closing device is a plate-shaped guide member 10, a plate-shaped moving member 20 which is slidably coupled to the guide member 10, as described in Korean Patent Registration No. 10-0865967, and a guide Both ends are rotatably coupled to the member 10 and the movable member 20, respectively.

Here, the elastic unit 30 is configured to be rotatable to the guide member 10 and the moving member 20 through the hinge pin 31, for this purpose, the guide member 10 and the moving member 20 The hinge pins 31 form assembly holes 19 and 29, which can be assembled into the elastic unit 30, respectively.

However, the opening and closing device of the conventional slide type mobile phone according to the related art, the elastic unit is provided by the hinge pin to be rotated, the assembly time according to the assembly of the opening and closing device takes a lot of time and the unit cost due to the hinge pin There was an issue that was raised.

In addition, the opening and closing device of the conventional slide type mobile phone according to the related art, because the hinge pin is directly connected to the hole formed at each end of the rotating plate of the elastic unit is directly applied to the rotating plate that the elastic force of the elastic unit is rotatably connected to the hinge pin. There was a problem that the reliability of the switchgear according to the rotation is deteriorated.

Accordingly, the present invention is devised to solve the above-described problems, the rotating plate is fixed to the first unit and the movable plate fixed to the second unit to form a rotation hole, the hinge device is inserted into the rotation hole to be rotatable The hinge pins can be eliminated by forming the rotating protrusions and the locking protrusions at one end of the rotating movement bar and the fixed fixing bar, respectively, thereby reducing the time for assembling the hinge device, and also the hinge pins. It is an object of the present invention to provide a slide type mobile phone opening and closing hinge device to reduce the unit cost due to the exclusion.

In addition, another object of the present invention devised to solve the above-described problems, the rotating plate is fixed to the fixed plate and the second unit fixed to the first unit to form a rotating hole, the insertion hole can be rotated The hinge and locking projections are formed on one end of the pivoting movement bar of the hinge device and one end of the pivoting fixing bar, respectively, so that the elastic force of the hinge device is applied to the projection rather than directly applied to the rotation projection. It is to provide a slide type opening and closing hinge device of a mobile phone to maintain the reliability of the device.

The present invention for achieving the above object is a plate-shaped fixed plate that is fixed to the first unit, and the second unit is provided by fixing the fixed plate on the back so as to be movable in the first unit and slide along the fixed plate; An opening and closing hinge device for slidingly opening and closing the second unit with respect to the first unit by rotatably connecting one end to the fixed plate and the moving plate, wherein one end is connected to the fixed plate to prevent rotation and separation. The rotation fixing bar is provided to be able to act on the part to be prevented from detachment and is slidably stacked on one surface of the rotation fixing bar, and one end is connected to the moving plate to prevent rotation and separation. , The elastic force is a movable bar for rotation and provided to be able to act on the part to be prevented from detachment, the fixed bar and the movable bar for rotation Each end of the other end of the lock is characterized in that it comprises a plurality of elastic members provided to provide an elastic force.

 Here, the fixing plate is inserted into the rotation hole formed at one end of the rotation fixing bar on the plate is characterized in that the rotation insertion protrusion protrudes to be rotatable.

In addition, the movable plate, the guide grooves are formed at both ends so as to be movable by inserting both ends of the fixed plate to both inner sides, the plate is slidably coupled to the fixed plate to be rotatably connected to one end of the movable bar for rotation. It is characterized in that the rotating projection is formed projecting in the position opposite to the rotating insertion projection.

In addition, the rotation fixing bar, the rotation hole is drilled at one end so as to insert the rotation insertion protrusion formed on the fixing plate, and is locked to be inserted into the separation preventing hole so as to be spaced apart by a predetermined distance from the rotation hole. It is characterized in that the end is provided with a pair formed on one surface so that the separation preventing projections having a locking piece facing each other.

In addition, the pivoting movement bar may include a pivoting hole at one end so as to insert the pivoting protrusion formed in the movable plate, and the end of the pivoting hole may be rotatably inserted into the locking hole spaced by a predetermined distance from the pivoting hole. It is characterized in that the engaging projection having a locking projection piece is provided in pairs to face each other.

According to the slide type mobile phone opening and closing hinge device according to the present invention as described above, the rotating plate fixed to the first unit and the moving plate fixed to the second unit forms a rotation hole, is inserted into the rotation hole to rotate The hinge pins can be eliminated by forming the rotating protrusions and the locking protrusions at one end of the pivoting movement bar and one of the pivoting fixing bars of the hinge device, thereby reducing the time when assembling the hinge apparatus. In addition, it is possible to lower the unit cost due to eliminating the hinge pin, and furthermore, the elastic force of the hinge device is applied directly to the projection rather than directly applied to the pivoting protrusion, thereby maintaining the reliability of the hinge device.
