[0048] In one embodiment: drive plate 4 extends upwardly on the two sides and is provided with guide plates 43 outside the two side surfaces of hinge cup 2.

[0049] In one of the embodiments: the inner side of any one of the guide plates 43 is concave to form a clamping groove 44, and the buffer 5 is clamped and fixed in the clamping groove 44.

[0050] In one of the embodiments: the side wall of the hinge cup 2 extends outwardly to form a positioning column 23, which is supported on the end face of the clamping groove 44 and presses against the tail of the buffer 5.

[0051] In one of the embodiments: the buffer 5 is a self-resetting compression type hydraulic buffer.

[0052] Working principle: in the utility model, the hinge cup 2 and the hinge arm 1 are hingedly connected through the upper connecting rod 3 and the lower connecting rod 31. The upper connecting rod 3 and the lower connecting rod 31 are fixed on the hinge cup 2 and the hinge arm 1 respectively, and the opening and closing movement of the hinge is realized through the swinging of the hinge cup and the hinge arm.

[0062] Simplify the structure: The external buffer device makes the internal structure of the hinge cup 2 and the hinge arm 1 more simple, reducing the number and complexity of internal components, improving the stability and reliability of the overall structure.

[0063] 3, improve damping effect: Since the buffer 5 is installed externally and is not limited by internal space, a larger hydraulic buffer can be used to provide stronger damping force, improving the buffering effect when the hinge is closed and effectively reducing impact and noise.
