Electric opening-closing drive mechanism for automobile tail gate

Abstract

The invention relates to an electric opening-closing drive mechanism for an automobile tail gate. The electric opening-closing drive mechanism for the automobile tail gate comprises a motor, an electromagnetic clutch, a speed reducer, a loading plate, a support rod and a swing arm, wherein the motor, the electromagnetic clutch and the speed reducer are assembled on the loading plate; an output endof the motor is connected with an input end of the speed reducer; one end of the support rod is hinged with the tail gate; one end of the swing arm is connected with an output end of the speed reducer; the other end of the swing arm is hinged with the other end of the support rod; the electromagnetic clutch comprises a dynamic disc, a stator disc, and an electromagnetic coil for enabling the dynamic disc and the stator disc to close so as to produce force transmission after being electrified; the dynamic disc is assembled on one side of a first transmission gear and rotates along with the first transmission gear; the dynamic disc is of a separated structure; the stator disc is assembled on a first transmission shaft and rotates along with the first transmission shaft; and a following geardisc rotating along with the stator disc, and a speed measuring gear meshing with the following gear disc are fixedly arranged on the stator disc. The electric opening-closing drive mechanism for theautomobile tail gate provided by the invention has the advantages of reasonable structure design and stability in use.

Description

technical field [0001] The invention relates to an electric opening and closing drive mechanism for an automobile tailgate. Background technique [0002] The car tailgate has manual switch and electric switch mode. The electric switch mode generally uses motor, clutch, reducer, swing arm and support rod. The motor provides power, which is transmitted to the swing arm through the reducer, and the swing arm drives the support rod to move. To drive the opening and closing of the tailgate, among them, the clutch is used for power transmission between the clutch reducer and the motor. At present, the electric switch structure of the automobile tailgate is relatively complicated, and the clutch stability of the clutch is poor, which affects the use of the electric switch structure. Contents of the invention [0003] In view of the above problems, the present invention provides an electric opening and closing drive mechanism for an automobile tailgate with reasonable structural d...
