The invention discloses a protection mechanism of an electric tricycle. The protection mechanism comprises a movable frame, a buffer device, a fixed frame and a pressing plate, wherein sliding holes distributed in a rectangular array mode are formed in the two groups of vertical bent structures on the upper side of the fixed frame; three groups of frame screw holes which are distributed in a transverse linear array are formed in the fixed frame below the sliding holes; the other two groups of bent structures at the top of the fixed frame are provided with two groups of frame shaft holes of which the shaft axes are overlapped with each other; a bearing is arranged in the frame shaft holes; six groups of symmetrical nut holes are formed in the middle of the fixed frame; hexagonal grooves forlimiting the positions of nuts are formed in the nut holes; four groups of symmetrical block connecting holes are formed in the lower side of the fixed frame; the block connecting holes are counterbores; and an opening with a rectangular outline and used for reducing weight is formed in the vertical part of the lower side of the fixed frame. The protection mechanism of the electric tricycle has the effects of hanging goods and resisting impact of the tail of the electric tricycle, and is suitable for being widely popularized and used.
