Preferably, the linkage member applies pressure to the friction plate under the action of the elastic member, and the friction plate is limited between the opening of the shell and the linkage member. Through setting up the friction disc to increase the frictional resistance that will increase when the linkage rotates, in order to further avoid the door to reset under the dead weight effect and close.

Preferably, the linkage piece is provided with a blocking part extending between the friction plate and the movable shaft; the friction plate and the linkage piece are both annular and are sleeved outside the movable shaft, and the grid blocking part is annular. The friction plate is limited to move by the blocking part, so that the friction plate is convenient to assemble, and the contact area between the linkage part and the friction plate is increased.

Preferably, a thrust bearing is arranged between the elastic part and the linkage part, and the thrust bearing is sleeved outside the movable shaft. The elastic part is not directly contacted with the linkage part, but is contacted with the linkage part through the thrust bearing, when the linkage part rotates, the elastic part does not rotate or even distort and deform, so that the service life of the invention is ensured, the effective stress of the linkage part is ensured, and the use stability of the invention is higher.

Preferably, the movable shaft comprises a linkage section matched with the linkage piece, the linkage piece is provided with a positioning hole penetrating through the linkage section to give way to the linkage section, and the inner edge of the positioning hole and the outer edge of the linkage section are of a square structure. The movable shaft and the linkage part are not matched through keys or fixed together through fasteners, so that the assembly of the invention is more convenient, and the subsequent maintenance of the invention is also convenient.

The invention can apply rotation resistance to the movable shaft of the automobile door actuator, has the advantages of being convenient for the door to be opened manually and avoiding the door to be closed under the influence of self gravity, can provide stable mechanical static friction resistance for the movable shaft and the movable arm, and has more stable use and longer service life; meanwhile, the invention can also adjust the resistance according to the dead weight of various vehicle doors, and has wider application range.
