Electric stay bar of electric tail door opening and closing system
A tailgate, electric technology, applied in door/window accessories, power control mechanism, wing fan control mechanism, etc., can solve the problem that the radial force of the strut is prone to bending deformation, the water and ice of the tailgate strut, etc. The tailgate cannot be closed tightly, so as to achieve the effect of increasing reliability and resistance to radial impact loads, avoiding potential safety hazards and having a compact structure.

Problems solved by technology
[0002] In the prior art electric tailgate opening and closing system, the outer sleeve of the electric tailgate stay is made of plastic, but the strength of the plastic sleeve is insufficient. Under low temperature conditions, the tailgate stay may accumulate water and freeze, causing the plastic sleeve to be damaged. The displacement of the tube weakens the radial support of the strut, and the radial force on the strut tends to cause bending deformation, which affects its service life and may cause the tailgate to fail to close tightly; in addition, in extreme cases, the spring on the strut It is also possible to completely break away from the tailgate strut mechanism and pop up, thereby causing personal injury, and there is a certain potential safety hazard; therefore, it is necessary to design an electric strut with good safety performance and a stable structure

According to an electric stay bar of an electric tail door opening and closing system, an encoder is arranged above a supporting frame, the upper end of a motor is embedded into the supporting frame,a coupler is arranged at the lower end of the motor, and a coupler shock pad is arranged between the motor and the coupler. A bearing is arranged below the coupler and arranged in an auxiliary coupler, a lead screw sequentially penetrates through the auxiliary coupler, the bearing and the coupler, and a dustproof sleeve is arranged between the auxiliary coupler and the lead screw. A nut sleeve isarranged outside the lead screw, a nut outer pipe is arranged outside the nut sleeve, and a metal sheath is arranged on the outer surface of the nut outer pipe. The outer side of the motor is providedwith a fixed iron inner pipe, and the fixed iron inner pipe extends downwards to a boss of the metal sheath and wraps the boss of the metal sheath. The electric stay bar is compact in structure, goodin stability, safe and reliable, potential safety hazards are effectively avoided, the performance of the supporting rod is kept stable, deformation is not likely to happen, and the service life is prolonged.
Description
technical field [0001] The invention relates to the field of electric tailgate opening and closing systems, in particular to an electric support rod of the electric tailgate opening and closing system. Background technique [0002] In the prior art electric tailgate opening and closing system, the outer sleeve of the electric tailgate stay is made of plastic, but the strength of the plastic sleeve is insufficient. Under low temperature conditions, the tailgate stay may accumulate water and freeze, causing the plastic sleeve to be damaged. The displacement of the tube weakens the radial support of the strut, and the radial force on the strut tends to cause bending deformation, which affects its service life and may cause the tailgate to fail to close tightly; in addition, in extreme cases, the spring on the strut It is also possible to break away from the tailgate strut mechanism completely and pop out, thereby causing personal injury, and there is a certain potential safety ...
