[0003] At present, with the development of society and the advancement of science and technology, most of the existing car tailgates are automatically opened and closed by electric struts. However, the existing car electric tailgate struts are not only prone to produce strong noise after long-term use, but also may cause the tailgate to open too much due to accidents or external forces, thereby causing the strut movable rod to be pulled off and damaged, and the tensile strength is low, which greatly reduces its service life. For this reason, we designed a tensile-resistant and low-noise car electric tailgate strut to solve the above problems. Summary of the invention
