Electric opening and closing system for automobile tailgate

Abstract

The invention discloses an electric opening / closing system for an automotive tailgate. A first ball pin and a second ball pin are correspondingly connected with the automobile tailgate and an automobile body. The electric opening / closing system comprises a motor, a lead screw, a lead screw nut, a reset spring, a nut outer pipe, a nut inner pipe, a wire hardness end sleeve, a middle sleeve and a movable sleeve, wherein the motor, the lead screw and the lead screw nut are sequentially connected in the axial direction; the reset spring, the nut outer pipe and the nut inner pipe are sequentially arranged in a sleeving manner in the radial direction; and the wire hardness end sleeve, the middle sleeve and the movable sleeve are sequentially connected in the axial direction. The first end of the middle sleeve and the second end of the movable sleeve extend inwards to correspondingly form end faces for limiting the movement of the rest spring along the axis. A fixed ball head and a movable ball head are both universal ball heads. The reset spring is a compression spring. The electric opening / closing system can integrate an ECU control system, the brace electric driving and the mechanical transmission, the hands of an owner of an automobile are completely liberated, the requirement of the owner on the comfort is met, and the electric opening / closing system has the beneficial effects of being capable of saving the cost, reducing the noise and good in waterproof effect.

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 the product of the improvement of the traditional pneumatic strut, and it is the trend of the development of intelligent and comfortable 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 ...

AI Technical Summary

Problems solved by technology

However, the disadvantages of the existing electric struts are that the manufacturing precision of the parts is high, the logic of the ECU control system is complicated, and the initial investment cost is large.

The previous generation of electric struts produced by our company has the defects of inconvenient loading operation, surface scratches, rust, noise, and not waterproof
