Scissor door hinge and automobile adopting same

Abstract

The invention relates to a scissor door hinge. A multi-connecting-rod supporting structure is matched with a restraining shaft seat to form a fifth axis, a hinge arm is hinged to the restraining shaft seat through the multi-connecting-rod supporting structure, the five axes share the same point, and the intersection point is located on an opening degree hinge piece, and the fifth rotating axis is arranged on one end, far away from a height shaft seat, of the hinge arm; the hinge arm is supported and the constraining force is increased for the hinge arm, so that the hinge arm is prevented from swinging, the structural stability is improved, a door is prevented from shaking during opening, the movement of the door in three directions is simplified into the cooperative movement of rotation of five rotating axes when the door is opened or closed, and the stability of the door during opening is improved; the scissor door is intelligently and electrically opened and closed, the whole movement process is simple, the influence on the structure of the door is small, the attractiveness and practicability of the scissor door are reserved, the smoothness and stability of door movement are improved, the door hinge is simple in structure, convenient to install and low in manufacturing cost, and mass production and generalization of the hinge are facilitated.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a scissor door hinge and an automobile using the hinge. Background technique [0002] In order to cater to the upgrading of domestic automobile consumption, more and more domestic OEMs are developing coupe projects. The design of scissor doors in coupe models is not only more attractive in appearance, but also solves the problem of insufficient opening space when parking spaces are tight. However, at present, domestic car companies have not mass-produced scissor door models, and most of the domestic models on the market are hinges for refitting. The hinges used for refitting are heavy in weight, large in appearance and shape, and difficult to install. [0003] The applicant previously applied for a Chinese invention patent with application number 2021 2017 3589.0, which discloses a car scissor door hinge, including a mounting seat and a hinge arm.

However, at present, domestic car companies have not mass-produced scissor door models, and most of the domestic models on the market are hinges for refitting.

Hinges for refitting are heavy in weight, large in appearance and shape, and difficult to install

[0003] The applicant previously applied for a Chinese invention patent with application number 2021 2017 3589.0, which discloses a car scissor door hinge, including a mounting seat and a hinge arm. The mounting seat is provided with an opening shaft seat and a height shaft seat. The arm includes a hinge connection part and a hinge driving part. An opening hinge is provided on the opening shaft seat, a height hinge is provided on the height shaft seat, and a universal rotation mechanism is arranged between them. One end of the opening hinge forms a first Rotation axis, the other end forms the second rotation axis, one end of the height hinge forms the third rotation axis, and the other end forms the fourth rotation axis, the first, second, third, and fourth rotation axes intersect at one point, and the intersection point It is located on the opening hinge, so that when the door is opened or closed, the movement in three directions of the door is simplified to the coordinated movement of four rotation axes. The whole movement process is simple and has little impact on the structure of the door, which improves the movement of the door. smoothness and stability, the structure of the door hinge is simple and convenient, the manufacturing cost is low, and it is convenient for the mass production and generalization of the hinge, but in the actual use process, the door is easy to shake during the opening process, and the door When used on the car door, the opening and closing output force is limited
