Abstract

The limiting type automobile door hinge comprises a movable hinge plate used for being fixedly connected with an automobile door and a fixed hinge plate used for being fixedly connected with the side wall of an automobile body, the movable hinge plate is rotationally connected with the fixed hinge plate through a hinge shaft, and the hinge shaft comprises a shaft rod and a first shaft sleeve which are connected in a matched mode; one end of the shaft rod is fixedly connected with the movable hinge plate, so that the shaft rod and the movable hinge plate synchronously rotate; the first shaft sleeve is arranged on the middle section of the shaft rod and fixedly connected with the fixed hinge plate. A ratchet wheel and pawl mechanism is arranged between the movable hinge plate and the fixed hinge plate, the ratchet wheel and pawl mechanism is installed on the hinge shaft and comprises a fixed disc, an inner ratchet wheel, a pawl and an inertia disc, the fixed disc is fixedly installed on the first shaft sleeve, and the inner ratchet wheel is fixedly connected with the disc face of the fixed disc. The pawls are annularly arranged in an inner cavity of the inner ratchet wheel and movably clamped in tooth grooves of the inner ratchet wheel. The method has the advantage of being capable of reducing personal injury.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a position-limiting automobile door hinge. Background technique [0002] The connection between the car door and the body is realized by the door hinge. The important part connecting the door and the body of the car is the door hinge, which provides convenience for passengers to get on and off the car.
