Document Type and Number:
WIPO Patent Application WO/2023/071345
Kind Code:
A1
Abstract:
The present invention provides a butterfly door hinge and a vehicle, and specifically relates to the technical field of vehicles. The butterfly door hinge comprises a mounting base, a vehicle door connecting arm, a hinge connecting arm and a limiting assembly; one end of the hinge connecting arm is hinged to the mounting base, and the other end of the hinge connecting arm is hinged to the vehicle door connecting arm; and the limiting assembly comprises a plane limiting part that is disposed on the mounting base and a limiting body that is disposed on the vehicle door connecting arm, and the limiting body is provided with a rotary outer contour. In the present invention, firstly, the hinge connecting arm is used for limiting the vehicle door swinging along a fixed point, and then the pose of the vehicle door is restrained by means of an abutting fit between the limiting body and the plane limiting part, so that the vehicle door may be maintained in a specific pose for opening towards the side in an upward opening process. Therefore, a butterfly door car may share one set of lock catch systems with a common side-opening car, thus reducing manufacturing costs. In addition, the structure of the present invention is simpler, and kinematic pairs are fewer; and the smoothness of vehicle door opening and closing processes is improved.
