Spaced apart from 216c By forming the oil inflow gap g1 with the inner surface 100b of the fixed hinge 100, the oil moved from the second oil filling space Sb to the side oil moving groove is the first oil filling space Sa. Characterized in that to be introduced into.

In the rotation hinge according to another embodiment of the smooth deceleration hinge device according to the present invention illustrated in FIG. 14, the rotating body fastening part 230 ′ is embodied in a male screw shape and is fastened to the rotating body. do.

Next, a description will be given of the operation process of the smooth deceleration hinge device of the present invention has a closed operation having the configuration as described above.

First, a process of assembling the hinge device A according to the present invention will be described.

First, the oil is injected through the oil injection hole 131 in a state in which the pivoting hinge 200 to which the O-ring 224 is fastened is fixed to the fixed hinge 100.

The oil injected through the oil injection hole 131 is introduced into the oil filling spaces (Sa, Sb), and when the oil is filled up to the air discharge hole (132), the sealing screws (P1, P2) are forcibly fitted to the oil. To prevent leakage.

In addition, the sealing cap 400 is mounted on the pivoting hinge 200 in a state in which the friction reduction washer 500 is fitted into the inlet frame 100c 'of the fixed hinge 100, and then completely ultrasonically fused. Seal

The operation of the hinge device A in the state in which the oil 300 is filled and the product is assembled as described above will be described.

FIG. 8 is an operation diagram of the case where the speed reduction member 240 is displaced from the upper surface 110a of the rotation stop member 110 and the rotor 20 is closed (BB line longitudinal cross-sectional view in FIG. 10A). 9, the speed reduction member 240 is located on the top surface 110a of the rotation stop member 110, and the rotor 20 is completely opened (CC line longitudinal cross-sectional view in FIG. 10 (c)). The operation diagram of is shown.

10 and 11 are cut in a right angle with respect to the longitudinal direction of the hinge device (A) in accordance with the rotation of the rotation hinge 200 in a state in which the rotation hinge 200 is coupled to the fixed hinge (100). The cross section seen from the boundary portion 220 side is shown.

FIG. 10A illustrates a view in which the rotor 20 is closed.

As shown in (a) of FIG. 10, in the state in which the rotor 20 is closed, the inner side surface 210c ″ of the insertion portion 210 of the pivoting hinge 200 is formed of the rotation stop member 110. It is in close contact with one side 110c ''.

Now, when the rotating body 20 is rotated by an external force, the rotating hinge 200 is rotated in the arrow direction (F direction) of Figure 10 (b) by the rotational force of the rotating body 20, at this time The oil 300 moves along an oil movement passage (thickness: d1) formed between the upper surface 110a of the rotation stop member 110 and the inner surface 220a of the boundary portion 220 to insert the portion 210 of the insertion portion 210. The second oil filling space Sb, which is a space formed by the inner side surface 210c ″ and the one side 110c ″, is moved.

The rotation body 20 is further rotated so that the speed reduction member 240 is larger than the area where the area where the speed reduction member 240 overlaps with the rotation stop member 110 does not overlap (strictly, the speed reduction member 240 is the rotation stop member 110). And the speed is gradually reduced from the time when it overlaps with the upper surface 110a of the speed reduction member 240 and the rotation stop member 110, so that a very small gap d2 is formed. The oil moving to the space Sb is subjected to a blocking control by the speed reduction member 240, so that the amount of oil moving is drastically reduced.

Therefore, the deceleration acceleration of the rotational speed of the rotation hinge 200 starts to increase from the time when the speed reduction member 240 is larger than the area where the area where the speed reduction member 240 overlaps with the rotation stop member 110 does not overlap.

As described above, when the inner side surface 210c 'of the insertion portion 210 is in contact with the other side surface 110c' of the rotation stop member 110 in a state in which the rotation speed is reduced, the rotation of the pivoting hinge 200 is performed. Is stopped, and as a result, the rotating body 20 is also stopped.

As described above, the rotation angle of the rotation hinge 200 is the central angle θ1 of the fan-shaped rotation stop member 110 and the inner surface 210c 'and the other surface 210c' 'of the insertion portion 210. Is determined by the angle θ2, and in particular, when the angle θ2 is 180 degrees, the rotation angle of the pivoting hinge 200 is determined by the center angle θ1.

In addition, the deceleration speed of the rotational hinge 200 depends on the thickness of the speed reduction member 240, that is, the size of the gap d2 between the speed reduction member 240 and the upper surface 110a of the rotation stop member 110. Determined by

That is, when the gap d2 between the speed reduction member 240 and the upper surface 110a of the rotation stop member 110 is large, the amount of oil moved increases, so that the rotation speed becomes relatively large, and the speed reduction member 240 and If the gap d2 with the upper surface 110a of the rotation stop member 110 is small, the amount of speed to be decelerated is large, and the damping speed is small, thereby opening more slowly.

In addition, the deceleration speed of the rotation hinge may be adjusted by the viscosity of the oil 300, in addition to the thickness of the speed reduction member 240.

In addition, the timing at which the pivoting hinge 200 is decelerated is determined by the area of the speed reduction member 240 as described above.

On the other hand, in the process of the rotation hinge 200 is opened and rotated as described above, the oil flow control rotor 217 is rotated together with the rotation hinge 200 so that the oil flow control plate 217b is fixed to the inner surface (100) of the hinge 100 Since the oil is in close contact with 100b), the oil in the first oil filling space Sa does not flow into the second oil filling space Sb through the oil moving slope groove 215a.

Now, a process of closing the rotating body 20 will be described based on FIG. 11.

When the rotating body 20 rotates in the closing direction (R direction) by applying an external force, since the upper surface 110a of the deceleration member 240 and the rotation stopping member 110 forms a very small gap d2, the oil 300 does not move to the gap d2 between the speed reduction member 240 and the upper surface 110a of the rotation stop member 110, but the first oil filling space Sa is along the oil movement inclined groove 215a. Flows into.

In more detail, when the rotation hinge 200 rotates in the closing direction (R direction), the oil flow control rotor 217 may rotate independently of the rotation hinge 200, and thus the oil flow control panel 217b. Is spaced apart from the opening rotation control surface 216c and forms an oil inflow gap g1 with the inner surface 100b of the fixed hinge 100, and thus along the oil movement slope groove 215a through this oil inflow gap g1. The introduced oil is moved to the first oil filling space Sa.

Thus, even when the rotor 20 is closed by moving the oil, it is possible to easily and smoothly rotate the pivoting hinge 200 without applying a large force, and the speed reduction member 240 stops rotating as the closing rotation proceeds. ) And the oil overlapping area is gradually smaller than the non-overlapping area, the oil is also moved through the oil movement passage (thickness: d1) formed between the upper surface 110a of the rotary stop member 110 and the inner surface 220a of the boundary portion 220. Since it is possible to more easily close the rotating body 20 by rotating the pivoting hinge.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.
