Abstract
The invention relates to an automatic opening mechanism for a trunk lid of a car based on a four-bar hinge, comprising a four-bar hinge, the four-bar hinge includes a driving arm, a driven arm, a fixed arm and a cover end mounting arm, and an automatic opening mechanism , the automatic opening mechanism includes a bracket assembly, a driving swing arm, and an electric strut. The active arm and the fixed arm of the four-link hinge are riveted through a riveted gear shaft. One end of the driving swing arm of the automatic opening mechanism is provided with internal teeth. It is meshed with the gear on the riveted gear shaft, and the other end of the drive swing arm is connected to the output end of the electric strut. The electric strut drives the drive swing arm to rotate around the riveted gear shaft, and the riveted gear shaft drives the four-linkage by driving the active arm to rotate. The hinge opens and closes, and the other end of the electric strut is connected to the bracket assembly; the present invention can be applied to an automobile trunk lid using a four-bar hinge to realize automatic opening / closing of the automobile trunk lid, and the structure is simple and the process Easy to implement and easy to install.
Description
[0001] [technical field] [0002] The invention relates to the technical field of auto parts, in particular to an auto-opening mechanism for a trunk lid of an automobile based on a four-link hinge. [0003] [Background technique] [0004] The opening / closing assist of the trunk lid of a car can improve the comfort of the user when opening / closing the trunk lid. At present, the conventional forms of assisting the opening / closing of the trunk lid are divided into: (1) Four-link hinge gas spring assist, Arrange the gas spring in the trunk lid of the four-link hinge; (2) assist the torsion spring of the gooseneck hinge, arrange the torsion spring in the trunk lid of the gooseneck hinge; (3) the tension spring of the gooseneck hinge For boosting, the tension spring is arranged in the boot lid on the gooseneck hinge. The above power-assisted forms cannot realize the automatic opening / closing of the trunk lid, and it is difficult to meet the needs of some users for the automatic open...
