Abstract

The invention discloses an electric opening and closing system for an automobile tailgate, which comprises: a screw nut sleeve and a screw nut, the screw nut sleeve is movably connected to the automobile body, and the screw nut is fixed on the screw nut Inside the sleeve; the screw rod, the first end of which is movably connected to the movable door of the tailgate of the car, the second end of the screw rod is set in the screw nut matched with it, and the screw rod is driven by the motor in the screw nut Do the spiral movement to drive the movable door of the tailgate of the car to be 0-150° relative to when it is closed. The invention integrates the control system, the electric execution and mechanical transmission of the strut, completely liberates the hands of the car owner, and meets the comfort requirements of the car owner. In order to meet the requirements of car owners with different heights on the opening height of the tailgate, the invention has the functions of memory, anti-pinch when opening the door, and anti-pinch when closing the door. At the same time, taking into account the possible power loss of the vehicle, it can adapt to manually closing the tailgate and then entering the electric opening mode again without the system not responding.

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...
