With their strong applicability, maneuverability, and low price, they are widely used in short-distance transportation fields such as households, urban and rural areas, individual rentals, factory areas, mining areas, sanitation, and community cleaning. Most of the widely used electric vehicle cargo boxes are fixed structures, and the goods in the cargo box need to be manually moved down. When the goods are heavy, it is more difficult to move. Some electric tricycles use cylinders to lift the car body and let the goods slide down, which may cause the center of gravity of the electric tricycle to tilt backward, which is not conducive to the safety of the rider. There is no resistance when the goods slide down, causing the goods to fall collectively, causing damage to the stability of the electric tricycle. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an adjustable cargo box for an electric tricycle, which solves the problem that when some electric tricycles use a cylinder to lift the compartment to allow the cargo to slide down, the center of gravity of the electric tricycle may be tilted backward, which is not conducive to the safety of the rider, and there is no resistance when the cargo slides downward, causing the cargo to fall collectively, thereby damaging the stability of the electric tricycle.

[0011] The utility model provides an adjustable cargo box for an electric tricycle. Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. An adjustable cargo box of an electric tricycle, wherein a connecting rod is driven upward by a cylinder to lift up. Since the connecting rod and a second connecting rod are fixed on the surface of an extension plate, the length of the second connecting rod is greater than that of the connecting rod. When the connecting rod is lifted upward, the inner box body is driven to deflect in a horizontal direction together with the second connecting rod under the fixing action of the connecting shaft, and one end of the inner box body is lifted up and the other end is made lower than the lifted end. At this time, the goods inside the inner box body can slide down. Since the center of gravity is always maintained at one end of the outer box body during unloading, the electric tricycle will not tilt due to the shift of the center of gravity during unloading.

[0013] 2. An adjustable cargo box of an electric tricycle, which can drive a second gear fixedly connected to the inside of a rotating shaft to rotate through a motor arranged inside a protruding end of the bottom of an inner box body, so that a gear meshing on the surface of the second gear drives a top opening and closing plate to rotate, so that the side of the inner box body opens and closes, and the cargo inside will slide down in the middle of the opening and closing plate, thereby preventing the stability of the electric tricycle from changing due to the concentrated sliding of the cargo, causing the rider to lose balance and fall off the driving seat of the electric tricycle.
