The utility model relates to the field of rear shock absorbers, and discloses a rear shock absorber linkage structure, including a frame, a swing arm, a shock absorber and a shock absorber linkage, wherein the shock absorber linkage includes a lower link and a triangle section, the upper part of the frame is hinged with the shock absorber, the middle part of the frame is hinged with the end part of the swing arm, and the lower part of the frame is hinged with the lower link. In the initial state, the end of the lower link close to the frame is lower than the other end, which can both improve the structural strength of the lower link and meet the design stroke requirement of the shock absorber. By setting the length ratio and angle of each side of the rear shock absorber linkage and the triangle section, the stroke relationship between the shock absorber and the swing arm can be optimized, so that the rider is more comfortable.
