Hinge hydraulic infinite check structure

摘要

A hinge hydraulic infinite check structure includes a paddle having at least one hydraulic aperture is rigidly fixed to a shaft. The pivot shaft is supported for pivoting movement within a case. The case includes a wall portion rigidly fixed to a cylindrically shaped inner surface and extends radially inward to the shaft. Pivoting movement of the pivot shaft forces the hydraulic fluid to move through the aperture from a first side to a second side of the paddle generating movement resistance. With the pivot shaft being stationary relative to the fluid chamber, equilibrium of fluid pressure of the hydraulic fluid at the first side and the second side of the paddle imparts a resistance to pivoting movement of the pivot shaft relative to the fluid chamber.

1. A vehicle door hinge structure comprising:
a body bracket; a pivot shaft having a first portion and a second portion; a hinge part having a first end and a second end spaced apart from the first end, the first end being attached to the body bracket by the second portion of the pivot shaft such that the hinge part pivots about the second portion of the pivot shaft between a closed position and an open position; and a hydraulic check structure including a paddle and a case, the paddle having a first side surface, a second side surface and an edge portion encircling the first side surface and the second side surface, a first section of the edge portion being rigidly fixed to the first portion of the pivot shaft for pivoting movement therewith, the paddle having at least one aperture extending from the first side surface to the second side surface; and a case non-movably attached to the body bracket and having a cylindrically shaped inner surface defining a fluid chamber therein, the pivot shaft being supported for pivoting movement relative to the case with the first portion of the pivot shaft being centered within the fluid chamber and the paddle extending from the first portion of the pivot shaft to the cylindrically shaped inner surface, the case including a wall portion rigidly fixed to the cylindrically shaped inner surface and extending radially inward to the pivot shaft, wherein the fluid chamber is filled with hydraulic fluid, the wall portion is shaped and dimensioned relative to the fluid chamber such that hydraulic fluid is prevented from moving from a first side of the wall portion to a second side of the wall portion, pivoting movement of the pivot shaft forces the hydraulic fluid to move through the aperture from one of the first side surface and the second side surface of the paddle to the other of the first side surface and the second side surface of the paddle, and with the pivot shaft being stationary relative to the fluid chamber, equilibrium of fluid pressure of the hydraulic fluid at the first side surface and the second side surface of the paddle imparts a resistance to pivoting movement of the pivot shaft relative to the fluid chamber.
