The invention relates to a shock absorber shell, a shock absorber, a suspension structure and a vehicle. The shock absorber comprises a shell, damping magnets, a movable shock absorption block and the like; the upper damping magnet part, the intermediate damping magnet part and the lower damping magnet part are sequentially arranged on the shell along a guide direction of the shell; the magnetic field intensity of the intermediate damping magnet part is lower than that of the upper damping magnet part and the lower damping magnet part, and at least one of the upper damping magnet part, the intermediate damping magnet part and the lower damping magnet part comprises at least two damping magnetic rings which are arranged up and down in parallel; the magnetic pole directions of every two adjacent damping magnetic rings are radial and opposite. When a vehicle drives stably, the movable damping block is positioned in the middle, and the damping force is relatively small; and when the vehicle suffers a relatively great impact, the movable damping block is positioned on the upper part or the lower part of the shell, the damping force is relatively large, so that the impact and the interference from a pavement can be well attenuated, and thus the damping force can be automatically adjusted according to the change of the vibration amplitude of the shock absorber.
