Document Type and Number:
WIPO Patent Application WO/2023/272780
Kind Code:
A1
Abstract:
A damping hinge, comprising a connecting assembly, a base body (5), a damping member (6), a torsion spring (7), a door fixing member (8), a fixing base (10) and a hinge arm (9), wherein the connecting assembly comprises a first connecting member (2), a second connecting member (1), a third connecting member (3) and a fourth connecting member (4); the base body (5) is provided with a first U-shaped groove (503), and the first U-shaped groove (503) is configured to accommodate a first hinge pin (12) used for fixing two sides of the fourth connecting member (4); the base body (5) further has a cavity (502), the extending direction of which is perpendicular to the first hinge pin (12), and the cavity (502) is configured to movably accommodate the damping member (6); the end of the damping member (6) that is away from the door fixing member (8) abuts against the first hinge pin (12); and the end of the damping member (6) that is close to the door fixing member (8) extends out of the fourth connecting member (4), and is configured to abut against the door fixing member (8) so as to be subjected to external pressing when the riveting angle between the fourth connecting member (4) and the door fixing member (8) is less than a preset angle. In the damping hinge, the damping member (6) thereof is movably mounted in the cavity (502) in the base body (5), and is convenient to disassemble and assemble, such that when a door is closed, a damping force generated by the damping member (6) slows down the speed of the door fixing member (8).
