Document Type and Number:
WIPO Patent Application WO/2019/120123
Kind Code:
A1
Abstract:
An improved buffering hinge, comprising a housing (1), a first rotational shaft (51), a U-shaped pin shaft (21), a hinge cup (2), a first linkage member (3), a second rotational shaft (52), a torsion spring (4), and a second linkage member (5), the hinge cup (2) being fixed onto a door panel. A damper guide member comprises a guide rack (6) provided between the second linkage member (5) and the housing (1). The housing (1) is formed by enclosing left and right side plates and an upper side plate (10), and is provided with a damper (8) and the damper guide member. The output direction of a piston rod (82) of the damper (8) is oriented to the upper side plate (10). The hinge effectively reduces its production costs, and overcomes noise generated by the friction between parts and the defect in the overall rotating smoothness of a product, thereby improving the overall quality and the market competitiveness of the product.
