Description

An opening device for an automobile gull-wing door

technical field

The invention belongs to the technical field of automobiles, and relates to a gull-wing door on an automobile, in particular to an opening device for an automobile gull-wing door.

Background technique

Gull-wing doors are generally hinged on the front fender or ceiling. They are named for their opening shape like wings. Because of their dynamic appearance, they give people the feeling of flapping wings. Compared with traditional doors, they are more convenient for passengers to enter and exit. And luggage placement, often used in sports cars.

The gas spring is an elastic element with gas and liquid as the working medium. It is composed of a pressure tube, a piston, a piston rod and several connecting pieces. It is filled with high-pressure nitrogen. The pressure is equal, but the cross-sectional area on both sides of the piston is different. Under the action of the gas pressure, the pressure is generated to the side with the smaller cross-sectional area. Unlike the mechanical spring, the gas spring has a nearly linear elastic curve, which is easy to control and stable.

Automobile gull-wing doors have been widely recognized and loved by people since their generation, and have been continuously improved. For example, a patent (CN 201769657U) discloses a car with gull-wing doors, wherein the gull-wing doors are hinged on the top of the car. A telescoping mechanism controls the opening and closing of the doors.
