[0002] We also call electric bikes "electric cars". They are pure electric vehicles that are powered by batteries (batteries) and driven by electric motors (DC, AC, series-excited, externally-excited). Electric bikes are mainly used for sightseeing, patrolling, and transporting goods. Load-carrying electric cars are electric cars with a large cargo capacity, powered by human pedaling, and used for urban express delivery.

Through the vertical sliding column 16 and the vertical slide groove, the object support frame 1 can slide vertically on the top of the U-shaped frame 2;

[0023] The adjustment mechanism includes a first transverse threaded rod 10, one end of which is fixed with a second transverse threaded rod 11, the other end of which is provided with a hand wheel 13, the first transverse threaded rod 10 and the second transverse threaded rod 11 have opposite thread rotation directions, the outer sides of the first transverse threaded rod 10 and the second transverse threaded rod 11 are both threadedly connected with a transverse sliding plate 9, one end of the transverse sliding plate 9 is also provided with a transverse moving frame 8, the transverse moving frame 8 is located at the top of the U-shaped frame 2 and is slidably connected with the U-shaped frame 2, and a buffer assembly is also provided between the transverse sliding plate 9 and the transverse moving frame 8;

[0024] A transverse light rod 12 is fixed inside the U-shaped frame 2. The transverse light rod 12 passes through the inside of the transverse sliding plate 9 and is slidably connected to the transverse sliding plate 9. Through the arrangement of the transverse light rod 12, the transverse sliding plate 9 can slide on the outside of the transverse light rod 12, thereby enabling the transverse light rod 12 to limit the movement trajectory of the transverse sliding plate 9.

[0025] By rotating the hand wheel 13, the first transverse threaded rod 10 and the second transverse threaded rod 11 can be rotated, and the rotation of the first transverse threaded rod 10 and the second transverse threaded rod 11 enables the two transverse sliding plates 9 to slide outside the transverse light rod 12, so that the movement directions of the two transverse sliding plates 9 are opposite;

[0026] A partition is rotatably connected to the connection between the first transverse threaded rod 10 and the second transverse threaded rod 11 through a bearing, and the partition is fixedly connected to the U-shaped frame 2, so that the connection between the first transverse threaded rod 10 and the second transverse threaded rod 11 can be more stable, preventing the connection between the first transverse threaded rod 10 and the second transverse threaded rod 11 from bending;

[0027] The buffer assembly includes a hydraulic cylinder 14, and the hydraulic cylinder 14 is arranged on both sides between the transverse moving frame 8 and the transverse sliding plate 9, and a rigid spring 15 is arranged between the transverse moving frame 8 and the transverse sliding plate 9 and on the outside of the hydraulic cylinder 14;

[0029] Working principle: By rotating the hand wheel 13, the first transverse threaded rod 10 and the second transverse threaded rod 11 can be rotated, and the rotation of the first transverse threaded rod 10 and the second transverse threaded rod 11 enables the two transverse sliding plates 9 to slide outside the transverse light rod 12, thereby making the movement directions of the two transverse sliding plates 9 opposite;

[0030] The movement of the two transverse sliding plates 9 enables the transverse moving frame 8 to move through the buffer assembly. The movement of the transverse moving frame 8 is through the second oblique rotating support column 7 and the first oblique rotating support column 5, so that the transverse moving plate 4 can slide on the outside of the load support frame 1, thereby adjusting the position height of the load support frame 1, and when the goods on the top of the load support frame 1 are vibrated, the buffer assembly can buffer and reduce the vibration to ensure smooth transportation of the goods.
