[0017] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present application. The present application is not limited to the description of the following embodiments.

[0018] like Figure 1 and 2 As shown, an electric gull-wing door mechanism for an automobile comprises a main body bracket 4, a gooseneck hinge 1 and an electric strut 2; the fixed end 11 of the gooseneck hinge 1 is connected to the main body bracket 4, and the fixed end 11 of the gooseneck hinge 1 is connected to the main body bracket 4 via a plug screw 6; one end of the electric strut 2 is connected to the gooseneck hinge 1 via a rotating shaft, and the other end of the electric strut 2 is provided with an electric strut tail fixing sheet metal piece 3.

[0019] like Figure 3 As shown, a bearing hole 41 is provided on the main support 4, a bearing 5 is fixedly provided in the bearing hole 41, and a connecting seat 42 for connecting with the car is fixedly provided on the outer side of the main support 4. An axial hole 14 is provided on the fixed end 11 of the gooseneck hinge 1, and a connecting hole 13 is provided on the movable end 12 of the gooseneck hinge 1. The fixed end 11 of the gooseneck hinge 1 is located in the middle of the main support 4, and the plug screw 6 is inserted in the bearing 5 and the axial hole 14, and the plug screw 6 is fixed to the bearing 5. The main support 4 is fixed to the car body by bolts connected to the connecting seat 42.

[0020] When in use, the electric strut 2 is in an extended state when the door is closed. When the door needs to be opened, the electric strut 2 retracts, which in turn drives the gooseneck hinge 1, which rotates clockwise with the plug screw 6 as the axis, and the door opens. During this process, the main bracket 4 is fixed to the vehicle body to play a supporting role, and the bearing 5 ensures the smoothness of the rotation during the rotation. Compared with the motor-lifting gull-wing door mechanism that uses the electric strut as the power source for opening and closing, this design has a simple structure and is easy to assemble, with reliable stability. Moreover, the adaptability is relatively high and the compatibility is relatively strong.

[0021] Refer to the attached Figure 1 As shown, in one solution of the present application, one end of the electric strut 2 is fixedly connected to the middle beam of the vehicle roof through the electric strut tail fixing sheet metal piece 3, the main frame 4 is fixedly connected to the middle beam of the vehicle roof, and the movable end 12 of the gooseneck hinge 1 is fixedly connected to the gull-wing door. When in use, the electric gull-wing door mechanism of the automobile is fixed to the vehicle body through the electric strut tail fixing sheet metal piece 3 and the main frame 4, the gooseneck hinge 1 is fixed to the gull-wing door through the bolt 7 and the connecting hole 13, and the electric strut 2 drives the gooseneck hinge 1 to realize the opening and closing of the gull-wing door.

[0022] Refer to the attached Figure 1 As shown, in one solution of the present application, the electric strut tail fixing sheet metal piece 3 is a right-angle sheet metal piece.

[0023] The above content is a further detailed description of the present application in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
