Automobile rotating door hinge

Abstract

The invention discloses an automobile rotating door hinge, which comprises a fixed arm and a rotating arm, wherein the fixed arm is fixedly connected onto a door post of an automobile body; the rotating arm is fixedly connected onto the automobile body; the fixed arm is respectively provided with an arc-shaped roller guide slot and an arc-shaped limit chute; and at least two limit pits are arranged in the limit chute. The rotating arm is provided with a roller mechanism and a limit ball mechanism, wherein the roller mechanism corresponds to the roller guide slot, and the limit ball mechanism corresponds to the limit chute. The roller mechanism and the limit ball mechanism respectively do relative slip in the roller guide slot and the limit chute, and thus, the fixed arm and the rotating arm can be rotatablely and glidingly connected. According to the automobile rotating door hinge, the opening angle of the automobile door is increased to the maximum degree; the opening and closing and limit function of the automobile door is realized; the arrangement of the hinge is realized by using a smaller space, therefore, the weakening to the door post is reduced, and the strength of the door post is ensured. Castings are respectively adopted to serve as the fixed arm and the rotating arm, therefore, the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an auto revolving door hinge. Background technique [0002] Generally, the door opening and closing action of a car is realized by a hinge. Usually, a car door hinge includes a body part connected to the car body, a door part connected to the door, and the body part and the door part are rotated through a pivot. This connection leads to When the door is opened and rotated, it is relatively close to the vehicle body, the rotation angle of the door is small, and the opening width of the door is limited; there are also structures such as connecting the body parts and the door parts through a long rotating arm and additional brackets, resulting in some complex revolving doors. The structure of the revolving door is more complicated, the hinge arrangement is inconvenient, the installation process is complicated, and the cost is high. position, so that the door can only be fixed at...
