Figure 4 shows that the hinge mounting member 12 is mounted to a cabinet body 76 that is mounted to a door panel 78 and that when the door panel 78 is displaced relative to the cabinet body 76 to a closed position, as in Figure 5 and As shown in FIG. 6, the hinge arm 14 collides with the slider 50, so that the slider 50 moves back and the piston rod 56 is slowly retracted into the buffer member 48, thereby generating a cushioning effect, that is, the door panel 78. The closing of the cabinet body 76 can be performed slowly and quietly. At the same time, the pair of wings 60 of the slider 50 will also leave the first support ears 42a and the second support ears 42b of the headstock 10 (as shown in FIG. 6 , one of the wings 60 leaves the first support ears 42a), and The recess 58 of the slider 50 is disengaged from the stop 38 of the header 10.

7 shows that when the hinge arm 14 is unfolded relative to the headstock 10, the piston rod 56 of the cushioning member 48 is extended to interlock the slider 50 until the pair of wings 60 of the slider 50 abut the head. The first support lug 42a and the second support lug 42b of the seat 10 are stopped (the one of the wings 60 is abutted against the first support lug 42a), and the recess 58 of the slider 50 is also associated with the headstock 10 The stop 38 abuts such that the slider 50 is stopped relative to the hinge arm 14 in a position that can be pushed against the cushioning action.

As described above, the cushioning device 16 of the embodiment of the present invention is mounted in the positioning manner of the headstock 10, mainly through the fitting portion 54 of the cushioning member 48 passing through the opening 64 of the fixing cover 52 and the headstock 10. The hole wall of the positioning hole 40 of the rear end wall 32 is positioned to be abutted, and the at least one hook portion 68 of the fixing cover 52 and the buckle portion 44 of the bottom wall 28 of the head block 10 are positioned with each other to make the buffer device 16 can be stably mounted on the headstock 10, and the pair of wings 60 of the slider 50 can be in the fixed cover 52 during the cushioning displacement of the slider 50 relative to the hinge arm 14. The linear sliding of the pair of chutes 70 provides a smooth and stable cushioning force. Accordingly, the present invention ensures that the cushioning device can provide a stable cushioning displacement stroke when the slider 50 is struck by the hinge arm 14, i.e., during the closing of the hinge arm 14 relative to the headstock 10.

It should be noted that the buffer displacement stroke of the above buffer device 16 can be planned. For adjustment, refer to Figures 8 and 9. In a further embodiment, the headstock 10 of the hinge has a guiding groove 80 at the bottom wall 28 of the headstock 10, and the guiding groove 80 is substantially It is perpendicular to the rear end wall 32 of the headstock 10. The fixing cover 52 of the buffer device 16 has an opening 82 communicating with the receiving groove 62. The buffering member 48 further includes a threaded portion 84, a guiding portion 86, and an adjusting member 88. The threaded portion 84 is a positioning hole 40 corresponding to the rear end wall 32 of the headstock 10 such that a portion of the threaded portion 84 of the cushioning member 48 can pass through the positioning hole 40. The guide portion 86 is a portion of the guide groove 80 that passes through the bottom wall 28 of the headstock 10 such that the cushioning member 48 is movable linearly displaced relative to the headstock 10. The adjusting member 88 is a threaded portion 84 that is movably screwed to the opening 82 of the fixing cover 52 to the cushioning member 48, and a portion of the adjusting member 88 is exposed to the opening 82 of the fixing cover 52. Thereby, the buffer member 48 is inserted into the movable groove of the fixed cover 52 to move linearly.

Further, when the adjusting member 88 is rotated, the cushioning member 48 is responsive to the rotation of the adjusting member 88 to be displaced relative to the headstock 10 to a first position, as shown in FIG. 10, the cushioning member 48 is The relative position of the slider 50 relative to the hinge arm 14 can also be changed, thereby adjusting the contact angle of the hinge arm 14 with respect to the headstock 10 to start to abut the slider 50 to generate a cushioning effect, that is, As shown, the door panel 78 begins to actuate the cushioning action relative to the cabinet body 76 at a closing angle a such that the door panel 78 can be slowly and quietly moved relative to the cabinet body 76 within such alpha angles. Similarly, when the adjusting member 88 is rotated again, and the cushioning member 48 is displaced relative to the headstock 10 to a second position, as shown in FIG. 11, the hinge arm 14 is folded with respect to the headstock 10 to start generating. When the buffering action is performed, the contact angle can be changed from the original α angle adjustment to a β angle. Therefore, when the door panel 78 is closed to the β angle with respect to the cabinet body 76, the buffering action is started, so that the door panel 78 is opposite to the The cabinet body 76 can be made to be slow and quiet in such a range of β angles.

In addition, when the hinge has the cushioning device 16 but does not use the cushioning action, as shown in FIG. 12, the adjusting member 88 may be rotated in advance to make the The cushioning member 48 is displaced relative to the headstock 10 to a third position, so that the slider 50 is away from the hinge arm 14 so that the hinge arm 14 does not touch when the hinge arm 14 is completely closed relative to the headstock 10. The slider 50, as such, provides a mechanism for the user to turn off the cushioning action.
