The damping buffer device can be applied to a sliding door and can also be applied to a sliding window, and the working principle of the damping buffer device is described by taking the application to the sliding door as an example.

The initial state of the invention is shown in fig. 3, at this time, the pulley assembly 15 on the door is clamped by the draw hook 6, the brake assembly is at the right end of the fixed body, and has no contact with the sliding part 7. When the door is opened rightwards, the pulley assembly 15 drives the drag hook 6 together with the sliding part 7 to move rightwards, so that the sliding part 7 stretches the second damper 4 and the linear spring 3. As the door continues to open, the second projection 72 at the right end of the slider 7 passes through the middle of the trigger 8 without contacting the two, as shown in fig. 4 and 5. As the door is opened further, the first protrusion 71 in the middle of the slider 7 contacts the trigger 8, as shown in fig. 6 and 7, the trigger 8 rotates counterclockwise and tilts with respect to the braking member 9 to avoid the slider 7, at this time, the braking member 9 and the first damper 10 remain stationary, and after the first protrusion 71 of the slider 7 passes through the trigger 8, the trigger 8 rotates clockwise under the action of gravity to a substantially vertical state, as shown in fig. 8. When the second pin 14 on the drag hook 6 slides into the inclined part from the horizontal part of the slide rail 131, the right end of the drag hook 6 tilts upwards, and the second pin 14 stops at the top of the inclined part of the slide rail 131 under the action of the tension of the linear spring 3, so that the drag hook 6 keeps the right end tilted state, and the pulley assembly 15 is released, as shown in fig. 9 and 10, at this time, the door is separated from the whole damping buffer device, and can be freely opened rightwards to be in place.

When the door is closed, the door is closed leftwards, when the pulley assembly 15 on the door impacts the draw hook 6, the second pin 14 at the right end of the draw hook 6 is separated from the inclined part of the slide rail 131, so that the right end of the draw hook 6 swings downwards to return, the draw hook 6 clamps the pulley assembly 15 again, as shown in fig. 11 and 12, the draw hook 6 and the sliding part 7 move along with the pulley assembly 15 in the door closing direction, the second damper 4 is compressed, the stroke of the second damper is recovered to 1/3, and the process is an initial buffering stage. When the slider 7 moves to the left to make the first projection 71 touch the trigger 8, the trigger 8 and the stopper 9 rotate together clockwise, and simultaneously pull out the stroke of the first damper 10 and rotate the movable end of the first damper 10 downward, as shown in fig. 13 and 14. After the triggering member 8 is separated from the first protrusion 71 of the sliding member 7, the braking member 9 slowly rotates counterclockwise under the combined action of the torsion spring 11 and the damping force of the first damper 10, in the process, the sliding member 7 continues to slide leftward, and the second protrusion 72 at the right end of the sliding member hits against the end of the braking member 9 connected with the first damper 10, as shown in fig. 15 and 16, which is a second buffering process. After the second buffering, the braking member 9 continues to rotate counterclockwise under the continuous action of the torsion spring 11, so that the second protrusion 72 of the sliding member 7 is disengaged from the braking member 9, as shown in fig. 17 and 18. Then, the door continues to move to the closing position in the door closing direction under the combined action of the linear spring 3 and the second damper 4, and the process is a third buffer.

According to the damping buffer device, the brake component with time delay (the damping effect of the first damper realizes time delay) is added, so that the larger door closing impact force can be counteracted by the brake component within the range of the strength of parts, and the door is slowly closed. Therefore, the elastic force of the linear spring 3 only needs to be designed as the minimum force value for pulling the door, and the damping force of the second damper 4 is designed as the minimum force value for enabling the door to be automatically closed finally, so that the best safety anti-pinch effect is realized while the door is opened easily.
