Description

Technical Field

[0001] The utility model relates to the technical field of automobile electric tailgates, in particular to an automobile electric tailgate lifting device. Background Art

[0002] The trunk of the vehicle (also the electric tailgate) can be opened and closed electrically without human intervention. The trunk is opened or closed electrically or by remote control. To open the trunk, just press the button in the car or the remote control key, and the trunk will open automatically. To close the trunk, press the close button in the trunk or the close button in the car, or the remote control key, and the trunk will close automatically. The basic structure of the electric tailgate is composed of two spindle drive rods. The drive rod is composed of an inner tube and an outer tube through the spindle driver, and mainly relies on the reaction force of the spring.
