[0002] With the improvement of people's living standards, the use of cars is becoming more and more popular. The electric tailgate braces have been recognized by more and more people because they make the opening and closing of the tailgate more convenient. People are enjoying the electric tailgate While the strut brings convenience, the noise generated by the electric strut is getting higher and higher. According to market research, most of the tailgates of automobiles will occasionally hear the spring and noise in the electric strut when opening and closing. The screw sleeve produces a "click" sound due to friction, which makes people feel uncomfortable. Working for a long time will not only affect the performance of the spring, but also change the coaxiality of the electric strut as a whole, resulting in The electric strut of the car is damaged, which affects the normal use of the car

The invention relates to a muting structure device for an electric brace of an automobile stern door. The muting structure device comprises an electric driving part, a screw rod part and a motion sleeve part. The electric driving part is axially connected with a first ball head part, an electric motor assembly and a connecting sleeve. The screw rod part comprises a screw rod which is connected with the connecting sleeve and can extend into the electric motor assembly. The screw rod is connected with a screw rod sleeve. An inner lining pipe is mounted at the exterior of the screw rod sleeve ina sleeving mode. A spring is mounted at the exterior of the inner lining pipe in a sleeving mode. A structure which reduces friction and then reduces noise is formed by the inner lining pipe, the spring and the screw rod sleeve. The muting structure device for the electric brace of the automobile stern door is simple in structure, the processing cost of mass production is low, and friction is reduced, so that the electric brace hardly can produce the noise when working, it can also be ensured that the electric brace ensures coaxiality reliable work, and overall performance of the electric brace is effectively improved.
