Description

Technical Field

[0001] The utility model belongs to the technical field of electric tricycles, and in particular relates to a modular tricycle bucket. Background Art

[0002] A tricycle is a means of transportation modified from a bicycle. It can carry people as well as goods. Whether in cities or rural areas, the most widely used ones are electric tricycles. Due to their small size and flexibility, it is very convenient to use electric tricycles to transport goods over short distances.

[0003] The cargo bed is a crucial component of a tricycle used for loading items. Currently, most tricycle beds are welded together. If a part or structure is damaged, it cannot be disassembled and replaced; the intact part or structure must be replaced along with the rest, making maintenance inconvenient and costly. Furthermore, existing technologies often use fixed-size cargo beds, limiting their cargo space and making it difficult to meet the demands of vehicle owners. Furthermore, fixed-size beds are incompatible with different vehicle frames, limiting their versatility. Therefore, a modular tricycle bed is urgently needed to address these issues. Utility Model Content

[0004] The present invention aims to address the technical problems existing in the prior art by providing a modular tricycle bucket with a rational structural design. The bucket of the present invention is manufactured and assembled in a modular manner, with the modules screwed and riveted together, making assembly and disassembly easy and enabling expansion of the bucket space. Furthermore, the modules can be disassembled and replaced in a targeted manner, making maintenance more convenient and significantly reducing maintenance costs.

[0005] The utility model adopts the following technical solutions to solve the technical problems existing in the known technology: a modular tricycle bucket includes a first bucket module and a third bucket module that are relatively arranged, and multiple groups of second bucket modules are arranged between the first bucket module and the third bucket module. The first bucket module is plugged and docked with the adjacent second bucket modules; two adjacent groups of second bucket modules are plugged and docked; the third bucket module is plugged and docked with the adjacent second bucket modules; the first bucket module includes a first main body device with a U-shaped structure and can be expanded, and a front guard is fixedly connected to one end of the first main body device. The utility model relates to a vehicle body comprising a vehicle body having a U-shaped structure and a plurality of first connectors arranged in parallel on one end and a railing on the other end; the second vehicle body module comprises a second main body device with a U-shaped structure and can be expanded, and a plurality of second connectors arranged in parallel are fixedly connected at both ends of the second main body device; the third vehicle body module comprises a third main body device with a U-shaped structure and can be expanded, a rear plate railing is installed at one end of the third main body device, and a plurality of third connectors arranged in parallel are fixedly connected at the other end; the first connector and the second connector, the second connector and the third connector, and the two groups of second connectors that are plug-in matched on the docking surface are all screwed connections.

[0006] The advantages and positive effects of the present invention are as follows: the present invention provides a modular three-wheeled vehicle bucket, which is formed by plugging and docking a first bucket module, multiple groups of second bucket modules and a third bucket module to form an entire bucket. In the actual assembly process, the cargo space of the bucket can be expanded by increasing the number of second bucket modules. At the same time, the number of second bucket modules used to assemble the bucket can be adjusted according to the length of the frame, so that the bucket can be suitable for different types of frames, and has good versatility. In view of the fact that the first bucket module, the second bucket module and the third bucket module all include a U-shaped and expandable main body device and multiple groups of plug-in parts, the bucket modules can be quickly assembled and installed during the bucket assembly process, and screw connections can be realized, thereby realizing modular installation of the bucket and facilitating the disassembly and replacement of only the damaged module when a module is damaged.
