Hereinafter, the operation of the slim tilting hinge and the electronic apparatus having the slim tilting hinge will be described.

Prior to the description, the slim tilting hinge of the present embodiment is formed of two sets as shown in FIG. 2, and is installed on both sides of the back surface of the electronic device. The hinge housing 110 of the slim tilting hinge is fixed to the back surface of the main body of the electronic device 1 and the tilting plate 140 is fixed to the stand 2. The stand 2 housed in the electronic apparatus is provided so as not to protrude from the back surface of the main body of the electronic apparatus and the hinge housing 110 is rotated by the tilting plate 140 coupled with the stand 2 from the main body So that the bottom surfaces (111, 113) face the back surface of the electronic device.

5 and 6 are a side view and a partially cutaway perspective view showing a state where the stand is housed in an electronic device, for example, a slim tilting hinge when the stand is not used, and an electronic apparatus having the same.

Referring to the drawings, the end of the slider 120 is located on the uppermost side of the hinge housing 110, and the bending portion 131b of the clip member 131 is in contact with the click groove of the slider 120 127, respectively. The click groove 127 provided between the plate portion 122 and the pivot shaft portion 124 is formed to be lower in height than the plate portion 122 so that the slider 120 returning after the sliding movement is caught by the bending portion 131b, To feel the click feeling.

The unused tilting link 141 of the stand 2 can be moved in the same direction as the first shaft pin P1 side which is axially coupled to the slider 120 by the second shaft pin P2 shaft- The entire stroke section of the tilting link 141 that rotates in the counterclockwise direction is reduced, thereby making the slim tilting hinge more compact in the longitudinal direction. That is, the tilting link 141 is provided to be slightly inclined in the direction opposite to the rotating direction of the slider 120 to reduce the stroke section of the tilting link necessary for normal rotation of the tilting link 141. At this time, The link supporting surface 115 is inclined so that it is possible to effectively prevent the tilting link 141 from rotating in the clockwise direction. The inclination of the second axis pin P2 with respect to the first axis pin P1 of the tilting link 141 does not exceed the thickness range of the hinge housing 100. [

When an external force is applied to the stand 2 by the user, the slider 120 and the tilting plate 140 of the slim tilting hinge 100 start to rotate in the direction of the arrow.

7 and 8 are side views showing a state in which the stand is rotated and exposed from the electronic apparatus, for example, a slim tilting hinge when the stand 2 is tilted about 45 degrees from the electronic apparatus 1. Fig.

Referring to the drawing, the slider 120 moves from the upper side to the lower side of the hinge housing 110, and the bending portion 131b of the freestop clam member 131 moves while rubbing the upper surface of the slider 120. The back surface of the slider 120 is in sliding contact with the flat washer 133 for smooth sliding of the slider 120. [

The tilting link 141 coupled to the slider 120 also rotates in the counterclockwise direction of the drawing by the linear movement of the slider 120 so that the tilting plate 140, which is axially coupled to the tilting link 141, Also rotate counterclockwise.

When the tilting link 141 rotates, the middle tilt 144 interposed between the hinge housing 110 and the tilting plate 140 also begins to slide. Even if the middle tilt 144 does not have a coupling structure such as a tilting projection and a projection receiving groove, the middle tilt 144 can perform the sliding rotation operation by the frictional force between the members. Even if the sliding operation is not performed, the stopper 145b of the tilting rotary shaft 145, It is possible to force the interlocking operation while being caught by the stopper latching bar 144d of the stopper 144.

9 and 10 are a side view and a partially cutaway perspective view showing a state in which the stand is exposed from an electronic device, for example, a slim tilting hinge when the stand 2 is opened at a maximum angle of about 150 degrees from the electronic device 1 .

Referring to the drawing, the slider 120 continuously moves from the upper side to the lower side of the hinge housing 110. At this time, the bending portion 131b of the freestop clam member 131 moves while rubbing against the upper surface of the slider 120 . The movement of the slider 120 can be ultimately limited by the slit 126.

The tilting link 141 rotates continuously in the counterclockwise direction of the drawing due to the linear movement of the slider 120 so that the tilting plate 140 and the middle tilt 144, which are axially coupled to the tilting link 141, Also rotate counterclockwise.

The stopper 145b provided on the tilting rotary shaft 145 of the tilting plate 140 is engaged with the stopper latching bar 144d and rotated together with the tilting and fixing unit 142 of the tilting plate 140. [ Since the middle tilt 144 and the tilting fixing portion 142 are provided to have the same rotation center and are rotated by dividing the rotation angle of the tilting plate 140 during operation of the tilting link 141, the entire thickness of the slim tilting hinge is reduced . For example, the middle tilt 144 rotates about 90 degrees from the reference plane? During the entire 150-degree rotation of the tilting plate 140, and the tilting rotary shaft 145 rotates about 70 degrees to reduce the thickness .

Since the closing operation of the stand 2 is the reverse order of the above-described operation, a detailed description will be omitted. The tilting plate 140 is rotated in the clockwise direction until the bending portion 131b of the free stop 130 is caught in the click groove 127 of the slider 120 so that the stand 2 can be rotated in the electronic device 1 And can be stored stably.
