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 and 113 are directed to the back surface of the electronic apparatus so that the bottom surfaces 111 and 113 can be exposed to the outside.

5 to 7 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.

5, when the stand 2 is unused, the cam 123 of the cam slider 120 is positioned at the wide portion 131 of the cam guide 130 of the hinge housing 110 do. Before the cam 124 of the moving cam 123 passes over the engaging portion 137 of the cam guide 130, when the applied external force is removed, the moving cam 123 is always held in the initial state by the elastic member 127, When the cam 124 of the moving cam 123 moves beyond the engaging portion 137 of the cam guide 130, the moving cam 123 is moved to the elastic member 127 And moves to the small width portion 133.

The unused tilting link 141 of the stand 2 has a first shaft pin P2 that is axially coupled to the tilting plate 140 as shown in Fig. The entire stroke section of the tilting link 141 that rotates in the counterclockwise direction can be shortened by being located further outward (clockwise) than the shaft pin P1 side, so that the slim tilting hinge can be made more compact in the longitudinal direction. That is, the tilting link 141 may be slightly inclined in a direction opposite to the rotating direction of the cam slider 120 to reduce the stroke area of the tilting link required for normal rotation of the tilting link 141. At this time, The tilting link 141 can be prevented from rotating in the clockwise direction by the bottom surface of the tilting link 141. [ The inclined position 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. [

The semi-auto operation of the cam slider 120 including the cam 124 and the engaging portion 137 as described above causes the stand 2 to move to the first tilting position inclined by 45 degrees with respect to the electronic apparatus 1 .

Then, when an external force is applied to the stand 2 again by the user, the cam slider 120 and the tilting plate 140 of the slim tilting hinge 100 start rotating in the direction of the arrow.

8 to 10 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 at 45 degrees or more from the electronic apparatus 1. Fig.

Referring to the drawings, the moving cam 123 of the cam slider 120 moves along the inclined surface of the small width portion 133 by an external force applied to the stand 2. The movement of the cam 124 of the moving cam 123 that moves while contacting the small width portion 133 of the cam guide 130 is resiliently pressed by the elastic member 127 but is also pressed against the hinge housing cover 118 By a friction block 128, which is shown in Fig. This is because the user does not adjust the inclination by grasping the stand 2 like the first inclination adjustment after the electronic apparatus 1 is supported on the floor surface with the first inclination at 45 degrees, So that the required inclination can be adjusted. That is, the slim tilting hinge of the present embodiment can realize the free stop function when the second inclination degree is adjusted, for example, between 45 degrees and 150 degrees by the moving cam 123 and the friction member 128.

9, the tilting link 141 interlocked with the cam slider 120 is rotated in the counterclockwise direction in the drawing by the linear movement of the cam slider 120, and thereby the tilting link 141 The axially coupled tilting plate 140 also rotates 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.

11 and 13 are a side view and a partially cutaway perspective view showing a state in which the stand is exposed from the 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 drawings, the moving cam 123 of the cam slider 120 moves along the inclined surface of the small width portion 133 by the external force applied to the stand 2, as described above. The maximum width of the small width portion 133 in this embodiment is the first oblique position where the stand 2 is supported at about 45 degrees with respect to the electronic device 1 and the minimum width W2 of the small width portion 133 is the width 1, the stand 2 is supported at about 150 degrees. In actual use, the first inclined position is a proper height when the electronic apparatus 1 is used by putting it on a desk or the like, and the second inclined position is a proper height when the electronic apparatus 1 is laid on the floor and used.

The tilting link 141 rotates continuously in the counterclockwise direction of the drawing by the linear sliding movement of the cam slider 120 so that the tilting plate 141 And the middle tilt 144 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. [ The middle tilt 144 and the tilting fixing portion 142 are provided to have the same center of rotation so that the rotation angle of the tilting plate 140 is rotated while rotating the tilting link 141. Thus the total thickness of the slim tilting hinge Can be effectively reduced.

Since the closing operation of the stand 2 with respect to the electronic apparatus 1 is the reverse order of the above-described operation, detailed description thereof will be omitted.

14 and 15 are views showing a slim tilting hinge according to another embodiment of the present invention. The present embodiment will be described mainly on the points different from the above embodiment, and the same reference numerals denote the same functions, and a description thereof will be omitted.

For example, the cam slider 220 includes a cam slider body 221, a moving cam 223 that is provided so as to be movable in a lateral direction on one side of the body 221, An elastic member 227, and a cam guide 230 provided on the inner wall of the hinge housing.

The cam slider body 221 is formed in a rectangular shape and includes a moving cam receiving portion 221a that opens to the rear side and a free stop receiving portion 221b that opens to the front side. The moving cam 223 and the elastic member 227 are provided laterally in the moving cam receiving portion 221a and the sliding movement force of the cam slider 220 is partially reduced in the free stop receiving portion 221b, In order to prevent unintended operation from occurring during the opening or closing operation. Details will be described later.

Further, a pivot shaft portion 222 is provided below the cam slider body 221 to engage with the tilting plate 140. The pivot shaft portion 222 has a shaft hole 222a which is opened to the side and has a predetermined thickness so that the second shaft pin P2 can be inserted therethrough.
