Accordingly, when the shaft 90 is immersed into the cylinder housing 10, the fluid resistor 70 receives resistance to movement by the fluid filled in the cylinder housing 10, whereby the front end of the shaft 90 (head cap is By slowly moving in response to the external pressing force applied to the combined portion), the external impact is alleviated.

On the other hand, as shown in Figure 6, the fluid resistor 70 is coupled to the end of the shaft 90 is to control the flow of the fluid when the shaft 90 emerges to transfer the resistance of the fluid to the shaft 90 .

At this time, the fluid resistor 70 is provided so that the outer peripheral surface is in close contact with the inner peripheral surface of the small diameter portion 55 of the cylinder housing 10, it is composed of a fluid guide member 77 and the joint 75.

The fluid guide member 77 is composed of a guide 60 and the actuator 71.

Thus, as shown in FIG. 6, the guide 60, the actuator 71 and the joint 75 are sequentially coupled to the ends of the shaft 90.

Here, the guide 60 is extrapolated and coupled to the end of the shaft 90, and as shown in FIG. 7, the guide 60 includes a body 61, a coupling 66, and an insertion 68.

The body portion 61 is formed in a circular shape, four fluid flow holes 62 are radially penetrated through the circumference.

Accordingly, the body portion 61 is provided in a shape in which two circular ribs 65 having concentric circles are connected by four support members 64, and at the top of the inner circular rib 65, the fluids are symmetrical to face each other. Guide grooves 63 are formed, respectively.

At this time, the upper surface of the circular rib 65 is formed slightly higher than the upper surface of the support 64 to support the lower surface of the actuator (71).

On the other hand, the coupling portion 66 is formed to protrude below the body portion 61, the coupling hole 67 is formed to be extrapolated to the shaft 90, a plurality of reinforcing ribs (66a) is formed on the outer peripheral surface.

In addition, the insertion portion 68 is formed to protrude upward on the upper portion of the body portion 61 and is fitted to the actuator 71, and forms four cut portions 68a to be provided in a cross shape.

On the other hand, the actuator 71 is the upper outer peripheral surface is in close contact with the inner circumferential surface of the small diameter portion 55 of the cylinder housing 50 so that the fluid can be easily moved to the fluid flow hole 62 of the guide 60, A circular through hole 72 is formed to be extrapolated to the insertion portion 68 of the guide 60, and the outer circumference is formed to be bent to be inclined upward by a predetermined angle and provided in a container shape having a predetermined depth.

Therefore, when the insertion portion 68 is inserted into the through hole 72 of the actuator 71, four passages are formed by the cutout portion 68a.

Here, the fluid moves inwardly of the actuator 71 when the shaft 90 moves, and moves along the four passages, and then through the fluid guide groove 63 and the fluid flow hole 62 of the guide 60. It moves along between the reinforcing ribs 66a of the engaging portion 66 of the guide 60.

Meanwhile, the joint 75 is formed in a cylindrical shape so as to be press-fitted to the end of the shaft 90 and extrapolated, and four protrusions 76 are radially spaced apart from the outer circumferential surface to protrude.

On the other hand, the elastic support portion 80 is used to relieve the moving shock of the shaft 90 by using the elastic force of the spring 81 when the shaft 90 is drawn out to the maximum and immersed in the cylinder housing 50 at the maximum. will be.

In this case, when the shaft 90 is immersed in the cylinder housing 50 to the maximum, the elastic support 80 is to relieve the moving shock on the shaft 90 by elastically supporting the fluid while the spring 81 is compressed. .

The elastic support portion 80 is inserted and coupled to the front end of the cylinder housing 50, it is composed of a bush 84, a spring guide 82, a press-fit seal 83, and a seal guide (85).

The bush 84 is press-fitted to the distal end of the cylinder housing 50 to support the outer circumferential surface of the shaft 90, and the spring guide 82 is inserted at both ends of the spring 81 to stably support the spring 81. Done.

Here, the press-in seal 83 prevents the fluid from flowing in the spring 81 direction, and the seal guide 85 supports the press-in seal 83.

Meanwhile, the inner circumferential surface of the cylinder housing 50 forms a small diameter portion 55 that can be in close contact with the upper outer circumferential surface of the actuator 71 provided on the fluid resistor 70, but has a large diameter portion at the center and the rear end. The first buffer portion 58 and the second buffer portion 56 are formed, respectively.

The first shock absorbing portion 58 and the second shock absorbing portion 56 form a large diameter portion having a relatively larger diameter than the small diameter portion, so that the actuator 71 provided in the fluid actuator 70 when the shaft 90 moves. Spaced apart from the outer circumferential surface of the fluid actuator 70 to be movable outside.

At this time, the first buffer 58 is formed in the center of the cylinder housing 50 to a predetermined length, the front and rear end to form a fluid guide surface (58a, 58b) which is inclined to facilitate the flow of the fluid, respectively.

Here, the second buffer portion 56 also forms a large diameter portion having the same diameter as the first buffer portion 58, and the fluid guide surface 56a is preferably formed at the front end portion.

The fluid guide surface 58b formed at the rear end of the first buffer portion 58 is preferably formed to be relatively longer than the fluid guide surface 58a of the front end portion.

Therefore, when the fluid resistor 70 enters the large diameter portion of the first shock absorbing portion 58, the fluid resistance is rapidly reduced, and when the fluid resistor 70 passes through the fluid guide surface 58b, the fluid resistance 70 is caused by the gradient of the fluid guide surface 58b. This gradually increases, thereby preventing a sudden change in fluid resistance.

In addition, a slight gradient is also given to the inner circumferential surfaces of the two small diameter portions 55, respectively, so that the fluid resistance gradually decreases or increases with the movement of the fluid resistor 70, so that the shock absorption of the shaft 90 is gradually achieved. It is desirable to be able to.

Meanwhile, the end of the shaft 90 to which the head cap 95 is coupled is inserted into and fixed in the fixing groove 17c of the main housing 10, and the cylinder housing 50 is slidably installed in the main housing 10.

That is, the cylinder housing 50 is installed in the main housing 10 to be slidable in the horizontal direction by the rotation of the driven reduction gear 230 of the reduction gear train 200, the guide rail in the main housing 10. The guide rail 17b is provided so that the guide rail 17b can be slidable.

8 to 10 will be described in detail the operation of the slide rail deceleration damper buffer system of the present invention.

8 is a view showing an operating state of the slide rail deceleration damper buffer system of the present invention, Figures 9 and 10 is an operating state diagram of the buffer damper of the present invention.

First, when the door is slid and opened, as shown in FIG. 8, the locking member 30 of the elastic actuator 40 interlocks with the operation of the door to slide the slide rail of the main housing 10 as shown by the arrow 300. Sliding along 13), the locking projection 35 of the locking member 30 is rotated at the end of the slide rail 13, the locking projection (38) protruding on the rear side of the locking hole (35) is the slide rail (13) It is fixed by being fitted to the locking portion (13a) of the.

Wherein the spring 20 is to maintain the maximum tension state, the door is to maintain the open state.

At this time, as the elastic actuator 40 moves, the reduction gears of the reduction gear train 200 engaged with the driving rack 33 are sequentially rotated.

At this time, the reduction gear train 200 is to convert the horizontal movement of the elastic actuator 40 to the rotary motion and at the same time reduce the rotation speed.

Meanwhile, the driven rack 53 engaged with the reduction gear train 200 moves as shown by arrow 310, and thus the cylinder housing 50 also moves, whereby the shaft 90 is withdrawn from the cylinder housing 50. Will be.

Here, the movement distance of the driven rack 53 of the cylinder housing 50 is moved relatively less than the movement distance of the drive rack 33 of the elastic actuator 40 by the reduction gear train 200, thereby the cylinder housing 50 Also, the travel distance of Nm can be reduced, so that the shock absorber 100 can be miniaturized.

As described above, when the user presses the door again after the door is opened, the elastic actuator 40 is released by the elastic force of the spring 20 while the locking mechanism 35 is released from the locking portion 13a. It is moved to the original position, accordingly, the reduction gear train 200 also reduce the reverse gears to move the cylinder housing 50 in the opposite direction of the arrow (310).

At this time, the fluid resistor 70 provided in the shaft 90 is subjected to the resistance of the fluid to apply the movement resistance of the cylinder housing 50 so that the door is closed slowly.

Here, the shaft 90 is to be immersed in the inner direction of the cylinder housing 50 again.

At this time, the fluid resistor 70 coupled to the shaft 90 starts to move in a state located in the small diameter portion of the first cylinder housing 50, as shown in FIG.

Therefore, as shown in the enlarged view, the fluid resistor 70 moves in a state where the upper outer peripheral surface of the actuator 71 is in close contact with the inner peripheral surface of the small diameter portion 55 of the cylinder housing 50.

At this time, the fluid moves to the inside of the actuator 71 as shown by the arrow, passes through four passages formed by the cutout portion 68a of the guide 60, and then the fluid guide groove 63 and the fluid of the guide 60. The minute amount is moved toward the elastic support part 80 via the flow hole 62.

Therefore, the shaft 90 is gradually moved to receive the resistance of the fluid during movement, thereby gradually absorbing the external pressure applied to the shaft 90.

On the other hand, as shown in Figure 10, when the cylinder housing 50 is moved to move the fluid resistor 70 to the first buffer portion 58, the outer peripheral surface of the upper end of the fluid resistor 70 is the first buffer portion 58 ) Is spaced apart from the inner circumferential surface of the large diameter portion.

Therefore, when the fluid resistor 70 moves through the first buffer section 58, the fluid forms a flow path along the same path as in FIG. 9 and at the same time as shown in the enlarged view of FIG. 10. Since the inner diameter of the large diameter portion of the buffer portion 58 is also moved toward the outer side of the fluid resistor 70, the amount of fluid moving per unit time is relatively larger than that of the small diameter portion 55, thereby allowing the shaft 90 to be moved. In this section, while receiving less fluid resistance, the movement speed is increased to have a buffering effect.

After that, the shaft 90 enters the small diameter portion 55 again when the fluid resistor 70 is out of the first shock absorbing portion 58, and the movement speed is reduced by receiving the same fluid resistance as in FIG.

In addition, when the fluid resistor 70 exits the small diameter portion 55 and enters the second shock absorbing portion 56, the fluid forms the same flow as the first shock absorbing portion 58, thereby providing a second buffering effect. You will get

In this case, the fluid resistor 70 of the shaft 90 sequentially passes through the small diameter portion 55, the first buffer portion 58, the small diameter portion 55, and the second buffer portion 56. The two buffers 58 and 56 pass through the buffer zone at a time difference to effectively absorb external shocks.

Therefore, in the present invention, the amount of movement of the elastic actuator 40 is transmitted to the shock absorber 100 through the reduction gear train 200, whereby the shaft 90 can move a relatively small movement distance, the shock absorber 100 In addition to miniaturization, the shaft 90 is prevented from warping and deformation, and the shock caused by the door is buffered in two stages through the first and shock absorbing portions 58 and 56, thereby moving the shaft 90. It is to be able to improve the durability by preventing damage to the cylinder housing (50).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and similarities.
