Abstract

The invention discloses an aluminium alloy double-rotating shaft hinge of a passenger car side door, which comprises a hinge upper profile (1), a hinge lower profile (2), and a hinge connecting profile all made of aluminium profiles, wherein the hinge upper profile (1) as well as the hinge lower profile (2), comprise a decorating edge (10), a mounting edge (4), a hinge shaft outer edge (6), and an open limit bulge (7); two ends of a transition arc edge (5) of the hinge lower profile (2) is connected with middle parts of strip edges (13) respectively; hinge shafts (9) are arranged at one ends of the strip edges (13); the other ends of the strip edges (13) form open limit edges (8); the hinge shafts (9) are wrapped inside the hinge shaft outer edges (6), and the hinge shafts (9) and the hinge shaft outer edges (6) can rotate relatively; end parts of the hinge shaft outer edges (6) are arranged to be circular arc edges (11); the hinge shaft outer edges (6) and the open limit bulges (7) are connected through arc faces (12); and the open limit edges (8) are correspondingly clamped with the open limit bulges (7).

Description

technical field [0001] The invention relates to a hinge used for a side cabin door of a passenger car, in particular to an aluminum alloy double-rotation axis hinge for a side cabin door of a passenger car, which belongs to the technical field of passenger car bodies. Background technique [0002] The side door hinge of a passenger car is a body component used to suspend the side door. Its specific structural form determines the opening angle and sealing performance of the side door, and also determines the relationship between the side wall outer panel and the side wall beam. The connection form affects the appearance and quality of the body. At present, the side door hinges of domestic passenger cars mainly include hinge-type single-axis hinges, rubber hinges, four-link hinges and six-link hinges. Due to the characteristics of single-axis rotation of the hinge-type single-axis hinge, the bus body must adopt a special structure to match the hinge-type single-axis hinge ins...
