Abstract

The invention discloses an electric opening and closing system for an automotive tail door. The electric opening and closing system for the automotive tail door comprises a lead screw nut sleeve, a lead screw nut and a lead screw, wherein the lead screw nut sleeve is movably connected to an automobile body, and the lead screw nut is fixed in the lead screw nut sleeve; the first end of the lead screw is movably connected to a movable door of the automotive tail door, the second end of the lead screw is arranged in the lead screw nut matched with the lead screw in a sleeved mode, and the lead screw is driven by a motor to make helical movement in the lead screw nut so as to drive the movable door of the automotive tail door to rotate by 0-150 degrees compared with the movable door in the closed state. According to the electric opening and closing system for the automotive tail door, a control system and supporting rod electric execution and mechanical transmission are integrated, both hands of an automobile owner are completely liberated, and the requirement for comfort of the automobile owner is met. In order to meet the requirements of automobile owners at different heights for the opening heights of the tail door, the electric opening and closing system for the automotive tail door has the memory function, the door opening anti-pinching function and the door closing anti-pinch function. In consideration of possible power loss of an automobile, the system can be adapted to the situation that the electric starting mode is started after the tail door is closed manually, and accordingly, response of the system is not available.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an electric opening and closing system for an automobile tailgate. Background technique [0002] The opening of the tailgate of a car is traditionally unlocked by the driver and passengers, and the tailgate is manually opened through a pneumatic strut. In the existing domestic automobiles, pneumatic struts are generally used, and only cars with higher specifications use electric tailgates, which are realized through electric struts. The electric strut is an improved product of the traditional pneumatic strut, and it is the trend of the development of the comfort of the opening and closing of the tailgate of the car. It has the advantages of compact structure, excellent dustproof and waterproof performance, and stable performance. However, the disadvantages of the existing electric struts are that the manufacturing precision of the parts is high, the logic of the ECU control s...
