Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, specifically to a cargo box for an electric tricycle with adjustable cargo space. Background Technology

[0002] In urban and rural logistics and individual transportation scenarios, electric tricycles have become a common tool for short-distance cargo transportation due to their flexibility, convenience, and low cost. Especially in places such as township markets, rural orchards, and farms, people often use electric tricycles to transport various materials such as agricultural products, agricultural supplies, and small-scale breeding equipment. In these complex and diverse transportation scenarios, the cargo box of traditional electric tricycles has exposed the problem of its unadjustable carrying space. Since the shape and size of goods vary greatly, from bulky furniture boards to slender bamboo poles, water pipes, and wide breeding nets, the fixed-size cargo box cannot meet the diverse loading needs. When transporting building materials in rural areas, the cargo box is not long enough for long timbers, so some timbers have to be suspended in the air. This not only poses a safety hazard during transportation but also makes it easy for the goods to fall due to insecure securing, causing losses. When transporting large agricultural product storage boxes, the insufficient width of the cargo box makes it impossible to load enough at once, requiring multiple round trips, reducing transportation efficiency and increasing time and labor costs. Utility Model Content

[0003] (a) Technical problems to be solved

A second latch 55 is provided on both the side wall and the side wall of the solid plate 53. A positioning hook 56 is fixedly connected to the outer wall of the solid plate 53. The outer wall of the connecting beam 51 is fixedly connected to the side wall of the base 1. The outer wall of the positioning hook 56 engages with the outer wall of the first latch 6. The rotating structure 5 is connected to... The other two side walls of the base 1 are connected to the connecting beam 51, and are connected to the solid plate 53 by the limiting hinge 52. When the solid plate 53 is rotated, the limiting hinge 52 limits its rotation angle to ninety degrees to avoid excessive flipping. After the solid plate 53 is rotated, the rotating frame 54 can continue to rotate. The side wall of the rotating frame 54 is provided with a second buckle 55 for connecting the hook 43. When the hook 43 of the sliding movable plate 41 passes through the position of the rotating frame 54, the hook 43 is then hooked by the rotating frame 54, thereby connecting the movable plate 41 and the rotating structure 5.

[0022] The limiting structure 2 includes a connecting strip 21, with a pin 24 inserted into the inner wall of the connecting strip 21. A connecting frame 22 is fixedly connected to the outer wall of the connecting strip 21. A limiting groove 23 is provided on the outer wall of the connecting frame 22. The outer wall of the bottom of the connecting frame 22 is fixedly connected to the outer wall of the base 1. The outer wall of the connecting strip 21 is fixedly connected to the outer wall of the first buckle 6. The bottom of the connecting frame 22 is connected to the base 1. The first buckle 6 is fixed on the outer wall of the connecting strip 21. The pin 24 can be inserted into its inner wall. The limiting groove 23 is provided on its outer wall. The sliding structure 4 can slide within the limiting structure 2. The limiting post 42 on the outer wall of the movable plate 41 slides within the limiting groove 23 to achieve smooth movement of the movable plate 41. The position of the movable plate 41 can be fixed by inserting the pin 24 into the positioning hole 44. When it is necessary to extend the length of the cargo space, the movable plate 41 is slid by pushing the limiting post 42. After reaching the extended position, the pin 24 is inserted to fix it. This design can flexibly adjust the internal space of the carriage according to the length of the cargo.

[0023] The sliding structure 4 includes a movable plate 41. Limiting posts 42 are symmetrically fixedly connected to the outer wall of the movable plate 41. Hooks 43 are fixedly connected to the side wall of the movable plate 41. Positioning holes 44 are symmetrically opened on the outer wall of the top of the movable plate 41.

The outer wall of the limiting post 42 is slidably connected to the inner wall of the connecting frame 22 through the limiting groove 23. The outer wall of the movable plate 41 is inserted into the outer wall of the pin 24 through the positioning hole 44.

[0024] In use, the adjustable cargo space electric tricycle's cargo box works in concert with the base 1, limiting structure 2, sliding structure 4, and rotating structure 5 to achieve flexible cargo space adjustment. The base 1 provides basic support for the entire cargo box, and the connecting frame 3 enhances its structural stability while differentiating the front and rear. A pair of limiting structures 2 are fixed to both sides of the outer wall of the base 1, and are composed of connecting strips 21, connecting frames 22, and pins 24. The bottom of the connecting frame 22 is connected to the base 1, and the first buckle 6 is fixed to the outer wall of the connecting strip 21. The wall can be plugged with a pin 24, and a limiting groove 23 is opened on the outer wall. The sliding structure 4 can slide within the limiting structure 2. The limiting post 42 on the outer wall of the movable plate 41 slides within the limiting groove 23 to achieve smooth movement of the movable plate 41. The position of the movable plate 41 can be fixed by plugging the pin 24 with the positioning hole 44. When it is necessary to extend the length of the cargo space, the movable plate 41 is slid by pushing the limiting post 42. After reaching the extended position, the pin 24 is inserted to fix it. This design can flexibly adjust the internal space of the carriage according to the length of the cargo and improve loading efficiency.

[0025] The rotating structure 5 is connected to the other two side walls of the base 1. The connecting beam 51 is connected to the base 1 and the solid plate 53 is connected by the limiting hinge 52. When the solid plate 53 is rotated, the limiting hinge 52 limits its rotation angle to ninety degrees to avoid excessive flipping. After the solid plate 53 is rotated, the rotating frame 54 can continue to rotate. The side wall of the rotating frame 54 is provided with a second buckle 55 for connecting the hook 43. When the hook 43 of the sliding movable plate 41 passes through the position of the rotating frame 54, the hook 43 is then hooked by the rotating frame 54, thereby connecting the movable plate 41 and the rotating structure 5.

[0026] The positioning hook 56 on the outer wall of the solid plate 53 can be engaged with the first buckle 6 to achieve fixation. When it is necessary to expand the width of the carriage or change the loading method, the solid plate 53 can be rotated to engage the positioning hook 56 with the first buckle 6, so that the solid plate 53 can be kept in the unfolded position. At the same time, the rotating frame 54 and the movable plate 41 are not connected, which makes it convenient to load and unload wider goods. During use, it can achieve the effect of multi-directional loading, thereby improving the space adaptability of the carriage.

[0027] Overall, the vehicle body, through the coordinated operation of its various structures, can flexibly adjust its cargo space to meet the loading needs of goods of different shapes and sizes. Compared with traditional fixed-space vehicles, it improves space utilization and loading flexibility, reduces transportation inconvenience caused by mismatched vehicle space, and enhances the practicality of electric tricycles in various transportation scenarios.
