Description

Compact buffering hinge Technical Field The utility model relates to the technical field of hinges, in particular to a compact buffer hinge. Background This section provides only background information related to the present application so as to enable those skilled in the art to more thoroughly and accurately understand the present application, and is not necessarily prior art. In modern daily life, hinges are widely used in connection and opening and closing mechanisms of various container furniture and electronic equipment. For promoting the use comfort level of hinge and extension its life, buffering five metals hinge has consequently been generated, and it is mainly through setting up the buffer, realizes the steady buffering of hinge in-process that opens and shuts, prevents impact and the noise that the quick closing caused. The buffer hardware hinge in the prior art is generally arranged in a hinge cup or a hinge arm, and has the problems of narrow internal space, high manufacturing precision requirement, limited buffer volume and the like. For this purpose, there are merchants that place the buffer outside the hinge cup and drive the buffer action by placing a drive assembly inside the hinge cup. However, the structure of the driving assembly in the existing hinge is complex, and the number of required parts is large, so that the product has a large volume, and the compactness and the miniaturization cannot be achieved, so that the design requirement of the product cannot be met. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides the compact buffering hinge, the driving support is arranged in the hinge cup to be in transmission fit with the buffer outside the hinge cup, the structure is simple, and the driving support is directly abutted with the cylinder body of the buffer to realize transmission connection, so that a transmission part is not required to be arranged between the driving support and the cylinder body to carry out transmission, the number of parts of a product is reduced, and the structure of the product is more compact. The utility model adopts the technical proposal for solving the problems that: A compact buffer hinge comprises a hinge cup and a hinge arm, wherein a rocker arm assembly is arranged between the hinge cup and the hinge arm to realize hinged opening and closing, a groove is formed in the hinge cup and is configured to accommodate at least part of the rocker arm assembly when the hinge is completely closed, and the hinge cup is characterized in that: The hinge cup comprises a hinge cup body, a hinge cup cover, a buffer assembly, a driving support and a buffer assembly, wherein the buffer assembly is arranged on the hinge cup body and is positioned outside the groove, and the driving support is rotatably arranged in the groove and is in transmission fit with the buffer; the buffer comprises a cylinder body and a piston rod arranged on the cylinder body, and the driving support is abutted with the cylinder body to realize transmission connection.
